Description
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.
