Electroweak physics and long-lived particles at LHCb

摘要

Extensions of the Standard Model (SM) of Particle Physics can be probed either through precision measurements of SM observables or via direct searches for processes beyond the SM (BSM). This proceeding focuses on precision measurements in the electroweak sector, in particular the properties of the ZZ boson, WW boson and top quark. Measurements of the WW and tt production cross-sections, as well as charge asymmetries, with an integrated luminosity of 5.1 and 5.4 fb1^{-1} of pppp collisions collected by the LHCb experiment, are presented for the first time. In consequence of the forward coverage of the LHCb detector, these results provide complementary probes on parton distribution functions compared to measurements performed at central rapidity. Well-motivated BSM candidates include mediators between the visible and dark sectors. In this context, recent results from searches for axion-like particles and heavy neutral leptons are also discussed.
