Abstract: Since 2015, fixed-target physics with LHC beams has been pioneered by the LHCb experiment, owing to its forward geometry and the gas target device known as SMOG. Leveraging the highest energy beams in fixed-target configurations presents a myriad of unique opportunities: accessing nucleon and nuclear Parton Distribution Functions at large Bjorken x; investigating cold nuclear matter effects at the onset of quark-gluon plasma formation; conducting hadronic production measurements of great relevance to cosmic ray physics. The newly upgraded gas target, SMOG2, is anticipated to significantly enhance both the achievable luminosity and the range of collision systems. In this presentation, I will provide an overview of the current status and the physics prospects of this unique QCD laboratory, which is currently unfolding during the LHC Run 3.
About the speaker:
Giacomo Graziani is a senior researcher and current coordinator of the experimental particle physics research at INFN, Sezione di Firenze (Italy), where he works since 2004. He obtained a PhD in Physics at the Università di Firenze in 2000, and was granted a Marie-Curie individual fellowship at LAL (Orsay, France) in 2001-2003. His fields of expertise, acquired through contributions to major experiments (NOMAD, NA48, ATLAS, BaBar, LHCb, ELI-NP), include flavour physics, data analysis, calorimetry and muon detectors. He pioneered physics with fixed targets at the LHCb experiment, serving as first convener of the related physics working group. He also served for several years as adjunct professor at the University of Florence, where he directed several PhD theses that received national recognition.
