LHCb - URL
The LHCb experiment at CERN is established as the world's leading flavour physics facility. The detector has been upgraded and has started a new phase of data taking in 2022. The experiment was designed to search for physics beyond the Standard Model (SM) of particle physics through precision measurements of CP violation and rare decays of heavy-flavored (beauty and charmed) hadrons produced at the LHC, but has expanded its physics program to include spectroscopy studies, QCD and electroweak physics, heavy ion and fixed target opportunities and long-lived particle searches. Results from the LHC to date continue to demonstrate that the Standard Model effectively describes phenomena up to an energy scale of O(1TeV). However, there must be physics beyond the SM, as the model cannot explain the matter-antimatter asymmetry observed in the Universe, neutrino masses and dark matter, among others. With the upgraded apparatus, the experiment will open the window to a new and exciting era with a higher discovery potential.
Particle physics experiments involve scientific, technological and computational challenges. The increase of luminosity in this new data-taking period has implied shifts of paradigm in data-acquisition methods, computing and analysis techniques, which are all challenges in the context of large-scale, global, collaborative and competitive research. Several fields of physics and engineering are called for this task. Specific contributions from the LHCb group at La Salle are: the commission and operation of the newly upgraded Calorimeter detector; the physics exploitation and its interplay with theory in radiative b-hadron decays; high-performance computing, reconstruction techniques in a real time fashion, artificial intelligence and statistics for data science; exploring new ideas for expanding the scientific potential of the upgraded apparatus, as well as evaluating phase-II upgrade options and reconstruction algorithms to deal with the challenges and possibilities of the HL-LHC; and the development of fast simulation techniques. The project also aims to carry out outreach activities and dissemination of the scientific results of the experiment, and knowledge transfer to industry and other scientific communities.
