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...
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...
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...
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...
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...
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...
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...
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....
