Abstract:
The LHCb experiment has been delivering high-quality data since the start of LHC operations and continues to provide groundbreaking measurements. While originally designed for precision studies of b- and c-hadron physics, LHCb has evolved into a general-purpose detector in the forward region of proton–proton collisions. Within this broader scope, it has achieved electroweak measurements that are both competitive with and complementary to those of ATLAS and CMS. Recent advances in reconstruction techniques, further enhanced by the use of artificial intelligence, have highlighted the pivotal role that LHCb can play in future Higgs physics. This seminar will review these developments and present several preparatory measurements for the study of the Standard Model Higgs boson at LHCb. In addition, prospects for searches of physics beyond the Standard Model in the Higgs sector will be discussed, together with the crucial contributions expected from future LHCb upgrades. These studies aim to shed new light on the properties of the Higgs boson.

Introduction:
Lorenzo Sestini is a Senior Staff Researcher at the Italian National Institute for Nuclear Physics (INFN), currently based at the INFN Florence division. Since the beginning of his career, he has been a member of the LHCb experiment, contributing first to b-hadron decay studies and later to QCD, electroweak, and Higgs physics. Within LHCb, he has served as coordinator of both the Jet Reconstruction group and the “QCD, Electroweak and Exotica” working group. Beyond LHCb, he has played a leading role in studies for future colliders, particularly in the design and assessment of a detector for a potential Muon Collider. His research also includes contributions to the development of advanced calorimeter technologies for next-generation accelerator experiments.
