9th International Conference on High Energy Particle and Nuclear Physics in the LHC Era

6 Jan 2025, 07:00 → 10 Jan 2025, 18:00 Chile/Continental

Building A (Universidad Técnica Federico Santa María)

Ahmed El Alaoui

HEPNP2025 is the IX international conference on High Energy Particle and Nuclear Physics in the LHC Era (previously called High Energy Physics in the LHC Era). It will be held from the 6^th to the 10^th of January 2025 in the  Universidad Técnica Federico Santa María (UTFSM), Valparaíso, Chile.

The scientific program of the Conference will address a broad range of topics covering the main areas of high-energy particle and nuclear physics such as: Higgs and EW Physics, Neutrino Physics, QCD, Beyond the SM Physics, Dark Matter particle searches, Astroparticles, Nuclear Physics, Heavy Ion collisions, Gravitational Waves measurements,  Particle Detectors and Instrumentation, Future experimental facilities, and other topics.

We strongly encourage experimentalists and theoreticians from all around the world to participate to the conference to discuss the recent progress and latest development in high energy particle and nuclear physics. 

We invite students and young researchers to participate also in the HEP School, which is taking place the week after the conference, more information about the lectures and the applications including important dates is available on the shool website: https://indico.cern.ch/event/1441005/

10:15 BCM' system for beam abort and luminosity monitoring in ATLAS

The High Luminosity upgrade of the Large Hadron Collider (HL-LHC) at CERN will significantly increase the collider's particle density, presenting new challenges for the ATLAS experiment's detectors. To address these challenges, a new radiation-hard beam monitoring system has been developed to protect the inner silicon detectors and accurately monitor the increased luminosity. This system employs polycrystalline Chemical Vapor Deposition (pCVD) diamond sensors, coupled with a newly designed radiation-hard front-end ASIC, to ensure high performance under the HL-LHC's extreme conditions.
The upgraded system, known as BCM’, will replace the existing beam protection system and be integrated into the retractable part of the new all-silicon Inner Tracker (ITk) of the ATLAS experiment. BCM’ will not only safeguard the ITk by monitoring background activity and aborting the LHC beam in case of hazardous particle showers but will also serve as a luminosity meter for ATLAS. In addition, a slower Beam Loss Monitoring (BLM) system, developed by the LHC machine, will act as a backup to the BCM’.
Given the HL-LHC's more intense radiation environment, the BCM’ system must meet much stricter radiation tolerance requirements, including higher neutron equivalent fluence, total ionizing dose, and charged particle flux. Preliminary results from the prototype detectors using the new ASIC have shown promising performance in beam tests at CERN, indicating that the system is on track to meet the demanding specifications of the upgraded collider.

11:20 Quarkyonic Matter

I discuss Quarkyonic Matter as an explanation for observed characteristics of neutron star matter. I also argue that the onset of density of Quarkyonic Matter is near that of nuclear matter based on quark distributions measured in deep inelastic scattering. The appearance of Quarkyonic Matter in the phase diagram for QCD at finite temperature and density is quantitatively estimated.

11:55 New measurement of $K^{+} \rightarrow \pi^{+}\nu\bar{\nu}$ branching ratio at the NA62 experiment

The $K^{+}\rightarrow\pi^{+}\nu\bar{\nu}$ decay is a golden mode for flavour physics. Its branching ratio is predicted with high precision by the Standard Model to be less than $10^{-10}$, and this decay mode is highly sensitive to indirect effects of new physics up to the highest mass scales. A new measurement of $K^{+}\rightarrow\pi^{+}\nu\bar{\nu}$ decay by the NA62 experiment at the CERN SPS is presented, using data collected in 2021 and 2022. This new dataset was collected after modifications to the beamline and detectors and at a higher instantaneous beam intensity with respect to the previous 2016-2018 data taking. Using the NA62 datasets from 2016-2022, a new measurement of the branching ratio $\mathcal{B}(K^{+}\rightarrow\pi^{+}\nu\bar{\nu}) = \left( 13.0^{+ 3.3}_{- 2.9} \right)\times10^{-11} $ is reported, and for the first time the $K^{+}\rightarrow\pi^{+}\nu\bar{\nu}$ decay is observed with a significance exceeding $5\sigma$.

Speaker: Evgueni Goudzovski

12:30 Extracting Proton 3D structure with AI: Highlights of the EXCLAIM project

Recent advances in nuclear theory, QCD phenomenology and experiments at the future EIC could soon lead us to both penetrate and visualize the deep structure of visible matter, answering questions that could not even be afforded before. In particular, deeply virtual exclusive experiments are believed to be probes of the orbital angular momentum of the proton's constituents, as well as of its 3D spatial structure. I will present results of the EXCLusives with AI and Machine learning (EXCLAIM) program centered on going beyond simple regression analyses that allow us to gain information from experiment from a quantitative analysis of the underlying correlations in the data.
