Aula B (Dipartimento di Matematica e Fisica)

The exciting discovery of the Higgs boson by the LHC experiments in 2012 has triggered a change of paradigm. The Higgs particle, which formerly was the object of experimental searches, has itself become a tool in the search for New Physics (NP). Although the Standard Model (SM) of particle physics has been extremely successful in the explanation of the experimental data, NP extensions beyond the SM (BSM) are are studied in order to answer some of the puzzles of nature, that cannot be explained within the SM. In view of the null results in the direct search for NP (discarding recent hints in the diphoton excess at 750 GeV that need further data for more conclusive interpretations) precision measurements in the Higgs sector play a crucial role. With the LHC run2 operating at 13 TeV and the collection of more data precision Higgs physics becomes feasible. I will present for selected BSM extensions what we can learn from precision investigations of the Higgs data and how new physics models might be distinguished.
