Special colloquium: Extending the physics reach of the fixed-target program at the LHCb experiment

Start: End: Location: CP-03-123
Dr. Chiara Lucarelli will present the topic "Extending the physics reach of the fixed-target programme at the LHCb experiment" on October 9.

Abstract:

Owing to the injection of gas into the LHC beampipe while multi-TeV proton or ion beams are circulating, the LHCb experiment has the unique possibility to be operated as the as-of-today highest-energy fixed-target experiment. During the LHC Run 2, data were collected with injected helium, neon and argon and their analysis has given access to a previously unexplored kinematic region, providing unique inputs to several research fields, such as the nucleon structure, heavy-ion physics and astrophysics. The system has been significantly improved for Run 3 with SMOG2, a dedicated storage cell for the gas and a new injection system, and now offers increased luminosities and the possibility to inject non noble gases, expanding even more the physics opportunities of the LHCb fixed-target program.

In this talk, the physics reach and the technical challenges of the SMOG and SMOG2 systems will be discussed, with a particular focus on recent and planned measurements of great interest for cosmic ray physics.
