Ten years of Higgs boson measurements: what we know and what we don’t know — •Christian Grefe — Physikalisches Institut, Universität Bonn

One decade after the discovery of the Higgs boson, the ATLAS and CMS experiments continue to publish more and more precise measurements of the Higgs sector, so far confirming the expectations of the Standard Model. With the start of LHC Run 3 ahead – which will double the existing pp-collision dataset – we will review the current knowledge of the fundamental properties of the Higgs boson.

In addition to the Higgs boson couplings, understanding the width and the CP properties of the Higgs boson is crucial to shed light on the open questions in particle physics: Is there CP violation in the Higgs sector? And are there invisible Higgs boson decays which would allow it to couple to a dark sector beyond the Standard Model? We will review the currently available measurements, their limitations and what to expect from Run 3 and beyond.
