51. Effective theories in the Higgs sector

Joergen Sjoelin (Stockholm University (SE))

06/01/2023, 15:15

A general and conceptual introduction to effective field theories (EFT) is given and applied to EFT extensions of the Standard Model. The focus of the talk is on on the Higgs sector and examples of recent LHC experimental constraints from single and di-Higgs production are discussed. To be exploited to its full power EFTs requires complex analysis techniques involving multiple measurements,...

52. Beyond-SM Higgs at the LHC

Santeri Laurila (CERN)

06/01/2023, 16:00

An extended Higgs sector, with a structure richer than the single Higgs doublet field of the Standard Model (SM), could solve many shortcomings of the SM. Experimentally, it could manifest as production of additional, beyond-SM scalar bosons at the LHC, as well as deviations from SM predictions for the SM-like 125 GeV Higgs boson. In this talk, a selection of recent experimental results from...
