12 Unveiling the nature of dark matter: a multi-faceted search program

Unveiling the nature of dark matter is one of the major endeavours of our century.
The search for dark matter is developed across multiple channels and with different techniques.
I will review the main candidates for particle dark matter and introduce how we tackle the challenge of discovering them.
I will focus especially on indirect dark matter searches, which aim to identify the nature of dark matter and narrow down the parameter space of different dark matter candidates by using data from astroparticle experiments on ground and in space.
I will present advanced techniques recently proposed to extract the most out of the great wealth of data we have at our disposal.
I will finally provide some prospects for future observations.

14 Dark Matter Searches in Colliders

The quest for dark matter (DM) is at the forefront of the scientific programme of the LHC experiments. In this talk, I will briefly review the gravitational evidences for dark matter and what are the gross features that make a good DM particle candidate. I will briefly touch upon the modelling of DM production at colliders, and review the experimental procedures for a search for dark matter with the LHC general-purpose detectors ATLAS and CMS. Finally I will highlight some of the latest experimental results from those collaborations, focusing on the results with the full Run-2 (2015--2018) dataset.

Dark Matter and Beyond Standard Model Searches

16 CMB spectral $\mu$-distortion during phase transition in the Bound Dark Matter (BDM) model

Spectral distortions of the CMB provide independent and complementary probes to study energy injection processes in the early universe. In this work was obtained the spectral $\mu$-distortion associated with phase transition of the dark particles in the BDM model. Several scenarios were simulated numerically with parameters: $a_{c} = [4.9 \times 10^{-7}, 3.3 \times 10^{-6}]$, $ f_{eff} = [0,1]$, $v_{c}=[0,0.71]$, $f_{x}=$ $ 10^{-2}$, $ 10^{-3}$, $10^{-4}$, $10^{-5}$ and $10^{-6}$. Some constrictions were obtained for FIRAS sensivity for $ a_{c} < 1.68 \times 10^{-6} $ ($ f_{x} = 10^{-2}$, $ f_{eff} = 0.5 $) and for PIXIE sensivity $ a_{c} > 1 \times 10^{-6} $ ($ f_{x} = 10^{-5} $, $ f_{eff} = 0.5 $).

Speaker: Raúl Henríquez (Universidad de El Salvador)

17 Exploring new physics through extended Higgs sector

In this talk I will give a short review of how the Higgs sector could give us some clues of physics beyond the Standard Model. Precision measurements of the Higgs coupling in colliders might tell us something about the scale of a more fundamental theory. By the other hand, and extended Higgs sector could work as a portal for WIMP Dark Matter. The talk will be based on 1912.01758 [hep-ph] and 2011.09101 [hep-ph]

Jet tagging is one of the tasks in High Energy Physics which can profit the most form data-driven and Machine Learning methods. In this talk I will start by reviewing the approaches that exist in the literature and the state-of-the-art of the field. Afterwards, I will show an illustrative example where an efficient tagger for Beyond Standard Model searches at the LHC can be built out of a very simple Machine Learning model.

22 Thermodynamics of a magnetized neutral vector bosons gas

This poster is dedicated to study the thermodynamic properties of a magnetized neutral vector boson gas at any temperature, with the aim to provide equations of state that allow more general and precise descriptions of astrophysical phenomena. The all-temperature analytical expressions for the thermodynamic magnitudes, as well as their non-relativistic limits, are obtained starting from the energy spectrum given by Proca's theory. With these expressions, and considering the system under astrophysical conditions (particle densities, temperatures and magnetic fields in the order of the estimated for Neutron Stars), we investigate the Bose-Einstein condensation, the magnetic properties and the equations of state of the gas, making a special emphasis on the influence of antiparticles and magnetic field. In all cases, the results are compared with their analogues in the low temperature and the non-relativistic limits. This allows us to establish the ranges of validity of these approximations and to achieve a better understanding of their effects on the studied system.

23 Identificación de partículas por medio de una red neuronal aplicable a los datos provenientes de un Detector de Radiación Cherenkov de agua de la utilización de una red neuronal

El objetivo general de este trabajo consiste en la identificación de partículas provenientes de cascadas de aire extensas de rayos cósmicos que inciden en la atmósfera.
A partir de una simulación realizada en Geant4 que contiene las características del detector de radiación Cherenkov de agua que se encuentra en la universidad del Valle de Guatemala, se generaron suficientes datos para que estos pudieran ser clasificados. Donde también se tomó información proveniente de Corsika, una simulación que permite conocer la afluencia de partículas y su nivel de energía dados ciertos parámetros, como lo son los metros sobre el nivel de mar, la latitud, etc. Estos datos fueron procesados por medio de una red neuronal la cual permitió la clasificación de partíclas.
Dado este modelo de clasificación, se tendrá un aporte significativo para la comunidad científica y en particular, a la comunidad de la Universidad del Valle de Guatemala.

24 Beyond the Standard Model at the LHC: Using Machine Learning to Search for New Physics in All-Hadronic ttbar Final States

In this talk I will cover two specific Beyond the Standard Model (BSM) analyses at ATLAS and CMS, both in the all-hadronic channels: a search for a supersymmetric (SUSY) partner to the top quark decaying to a new stable neutral particle and a SM top, and the other for heavy resonances decaying to a top+antitop (ttbar) pair. The searches utilize Run 2 data of proton-proton collisions delivered by the LHC between 2015-2018. The SUSY analysis selects for events by requiring a mass window on reclustered large-radius jets to identify top quarks and large missing energy carried away by the neutral final-state SUSY particles, which can be interpreted as a Dark Matter candidate. The ttbar resonance analysis will use a neural network architecture to identify boosted tops, triggering on events with significant activity in the calorimeters. The SUSY analysis has been published recently by ATLAS and observed no significant excess over the SM expectation, excluding SUSY top partners up to 1.25 TeV. The ttbar analysis is currently underway in CMS and expects to publish the results in 2021.

Dark Matter and Beyond Standard Model Searches

27 New Searches for Dark Sectors in Neutrino and Kaon Experiments

While incomplete, the experimental success and theoretical consistency of the Standard Model suggest that if we are to find new particles or interactions at low energies, they should be very weakly coupled to ordinary matter and likely organized in new secluded or "dark" sectors. In this way, our best chance for discovery lies in low-background and high-intensity experiments, such as neutrino and kaon facilities. In this talk, I will highlight some of the most promising channels for discovery of dark sectors in the MeV and GeV energies, and discuss new ideas for searches that can shed light on tantalizing anomalies in neutrino and nuclear data.

28 Axion dark matter search at CAST with the RADES detector

Cosmological and astrophysical observations predict that around 25$\%$ of the energy content of the universe is made of dark matter. The nature of dark matter is currently unknown and a lot of effort is placed in the hunt for dark matter. One of the candidates for dark matter is the axion, a particle first introduced to solve the strong Charge-Parity problem of the Standard Model.

The CERN axion solar telescope (CAST) is well known for its investigations of axions coming from the sun. However, in recent years the CAST Collaboration has in parallel introduced relic axions searches, using the haloscope method. In this talk we will introduce the Relic Axions Detector Exploratory Setup (RADES) detector geometries and and present the analysis strategy on a first data set acquired in 2018 with a pathfinder cavity. The results show the potential of this type of detectors to reach QCD axion sensitivity.

30 Very-high-energy photons and Neutrinos, and Gravitational waves from GRBs and Blazars

Very-high-energy (VHE; > 10 GeV) photons are expected from the nearest and brightest Gamma-ray bursts (GRBs). VHE photons, at energies higher than 300 GeV, have been recently reported by the MAGIC and H.E.S.S. collaborations for different bursts. Orbiting satellites and ground-based telescopes followed these bursts. We analyze the multi-wavelength observations and show that the high-energy photons are produced in the deceleration phase of the outflow, and some other processes to synchrotron in the forward shocks should be considered to adequately describe the LAT, MAGIC, and HESS photons with energies beyond the synchrotron limit. Besides, we talk about the short GRB 170817A, which was associated with producing gravitational waves from a binary neutron star merger. Finally, we talk about the detection of a prolonged flaring activity from blazar TXS 0506+056 in temporal and spatial coincidence with the energetic neutrino IceCube-170922A

31 Highlights from The HAWC Observatory

The High Altitude Water Cherenkov (HAWC) observatory is a wide-field-of-view (2sr) and high duty cycle (>95%) gamma detector that operates at an altitude of 4100 m in the state of Puebla, Mexico. Since 2015, HAWC has continuously surveyed the sky, providing a unique insight into the very high energy (>1 TeV) astrophysical sources. In this talk, I will discuss some of the exciting results of HAWC and also its indirect dark matter searches.

33 Study of gamma ray activity in blazars and some implications for neutrino emission

Blazars are the most luminous extrgalactic gamma ray sources. They are a type of Active Galactic Nuclei which are powered by material falling onto a supermassive black hole at the center of the host galaxy. They show sporadic bursts of activity with different time range. In this talk we present a 10 year data analysis of a sample of bright blazars detected by Fermi-LAT (0.1-300 GeV), in particular we present the Duty Cycle -the fraction of time that the source spends in active phase- for the sample. Also we present the consistence of this sample with the so called "blazar sequence" and how this analysis constrains possible counterpart of neutrino emission.

Speaker: Jose Rodrigo Sacahui Reyes (Universidad de San Carlos de Guatemala)

34 Potential of MATHUSLA for cosmic ray research

The main objective behind the MATHUSLA proposal is to build a large area hodoscope detector at ground level, close to the interaction point of the CMS detector, to look for the decay signals of neutral long lived particles (LLP) at the next HL-LHC runs in an environment with low background. LLPs are expected in the context of Beyond Standard Models, which try to solve open problems in fundamental particle physics. The idea behind MATHUSLA is to monitor a large volume of air (100 m x 100 m x 25 m) with a series of layers of tracking detectors to look for displayed vertices produced by the LLPs. The updated MATHUSLA design considers extruded scintillators for the tracking detectors. However, it has been also considered to add an extra layer of RPCs to enhance the extensive air shower detection capabilities of MATHUSLA to carry out cosmic ray studies in the 100 TeV - 100 PeV regime. In this talk, a brief introduction to MATHUSLA will be presented, with an emphasis on its sensitivity to cosmic ray detection. A comparison of its performance with that of other present and future cosmic ray facilities working in the same energy range as MATHUSLA will also be shown.

Speaker: Prof. Arturo Fernandez Tellez (Autonomous University of Puebla (MX))

35 A relativistic model for quasi-periodic blazars

Blazars are very bright extragalactic objects whose luminous intensity is variable in differents frequency-band spectra. It has been observed that PG1553+113 presents the same quasi-periodic variability in all the bands analyzed. One possible explanation for this behavior is that PG1553+113 is a binary black holes system. In this work it is proposed to improve the binary black hole model taking into account relativistic effects in addition to looking for new candidates whose variability can be explained in this way.

37 Active irreversible process in quantum field theory

We describe the dynamics of a quantum field coupled to a moving heat bath, in the formalism of the Markovian master equation for the field considered as an open system. We apply this to the superradiance of a rotating black hole, which provides a useful paradigm for understanding other irreversible active processes. Fermions can't superradiate, but work may be extracted from their motion-induced population inversion in the presence of two baths. We argue that this describes the triboelectric effect (the charging of rough surfaces by rubbing). We also apply this formalism to shock waves, fleshing out Zel'dovich's intuition that in this case "quantum mechanics helps understand classical mechanics”, and Ginzburg’s insight that "radiation during the uniform motion of various sources is a universal phenomenon rather than an eccentricity”. Finally, we argue that our interpretation of the triboelectric effect offers a qualitatively new mechanism for CP violation in fundamental physics.

40 Cathode Strip Chamber Upgrades for the Compact Muon Solenoid at CERN

The Compact Muon Solenoid (CMS) experiment at CERN is a general purpose detector designed to reconstruct particle collisions delivered by the Large Hadron Collider. Currently the LHC and its experiments are in the second long shutdown (LS2) period which allows for upgrades to their sub-systems. The muon spectrometer of CMS is extremely useful in such a busy hadronic environment, as it can identify clean signatures of outgoing muons. The Cathode Strip Chambers (CSC) are multi-layered gas cavities using wires (anodes) and strips (cathode) to read-out the ionization signals created by traversing particles. The CSCs are located on both end-caps of CMS, four stations on each side. Although the CSCs are performing very well with current accelerator conditions, their electronics will not be able to cope with the higher luminosity (data flux) of the planned High Luminosity LHC. In this talk I will introduce the technology used by CSCs, as well as an update on the LS2 upgrade to the chambers.

41 High performance data acquisition and processing based on programmable SoC for multichannel particle detectors

Modern high energy physics experiments are characterized by a large number of detectors with several channels per detector. This leads to high amount of data generated in short periods of time (~TB/Sec). All this data must be acquired and processed on line in order to apply complex algorithms for data reduction and filtering before storage for subsequent offline data analysis. The following presentation will briefly describe the high speed data acquisition front-end (DAQ), feature extraction and slow control based on FPGA/SoC technology applied in the context of COMPASS experiment at CERN. It will be presented a short description of the work in progress in the implementation of the DAQ in an array of electronic calorimeters (ECAL2) and the study of high speed electrical discharges propagation in Micro Pattern Gaseous Detectors.

45 Direct Dark Matter Searches

Results from cosmological observations show that 85% of the matter in the universe is cold dark matter. However, its fundamental composition remains unknown, with several theoretical proposals for beyond-the-Standard-Model dark matter particle candidates. Because dark matter is bound to the Milky Way galaxy in a "halo," there should be a measurable dark matter particle flux through Earth. I will present an overview of the field of dark matter direct detection, which aims to observe the interactions of dark matter particles in the halo with instrumented targets on Earth. I will focus on recent trends in the field, in particular the search for "low-mass" dark matter particles with the DAMIC experiment.

47 LAGO: El Observatorio Latinoamericano Gigante Estado Actual y Perspectivas Futuras

The Latin American Giant Observatory (LAGO) is an extended cosmic ray observatory composed by a network of water-Cherenkov detectors (WCD) spanning over different sites located at significantly different altitudes (from sea level up to more than 5000 m a.s.l.) and latitudes across Latin America, covering a huge range of geomagnetic rigidity cut-offs and atmospheric absorption/reaction levels. The LAGO WCD is simple and robust, and incorporated several integrated devices to allow time synchronization, autonomous operation, on board data analysis, and even remote control and automated data transfer.
This detection network is designed to measure the temporal evolution of the radiation flux coming from outer space at ground level with extreme detail. LAGO is mainly oriented to perform basic research in three branches: high energy phenomena, space weather and atmospheric radiation at ground level. It is an observatory designed, built and operated by the LAGO Collaboration, a non-centralized collaborative union of more than 30 institutions from ten countries.
In this work we will describe the scientific and academic primary goals of LAGO, by showing its current results, present status and future perspectives.

49 High Performance Computing at Universidad de Costa Rica

Computer Clusters have demonstrated to be a key tool in scientific research. New algorithms have been developed in several areas: bioinformatics, particle physics, nuclear physics, astrophysics, condensed matter, chemistry, engineering, economy, among many other fields. Over the last 10 years our university has been supporting research projects that need a lot of computer power to solve their problems. Nowadays, there are several computer clusters sparse over the campus that are close to their end of life. Each one was acquired for specific applications. Instead of replacing each one of the clusters, we have decided to build a Campus Cluster to serve all the scientific and academic staff, including students of course. This cluster is aimed to cover all the different necessities we could find, including GPU capabilities. We are expecting that this new Campus Cluster will be a key player in our research and also will allow us to make interesting collaborations in the Central America and the Caribbean region.
