Precision studies of the Higgs boson -- a window to new discoveries
Abstract: With the discovery of the Higgs boson, the last remaining constituent of the Standard Model of particle physics has been experimentally confirmed. However, the Standard Model does not answer several important questions about fundamental physics: What is the origin of dark matter?
Why is there matter but (almost) no antimatter in the universe? How can we describe gravity and quantum mechanics in a consistent way?
The Higgs boson is fundamentally different from all other known elementary particles, and thus it may arguably be the key to some of these questions. If this is the case, small (percent-level) deviations in the couplings of the Higgs boson are expected. Deviations of this magnitude can be tested at several proposed future experimental facilities, but their identification also requires precise theory calculations. This presentation will describe some of the challenges involved in these calculations, and insights to be gained from precision studies of Higgs properties and other electroweak bosons. I will also discuss the implications of another interesting precision measurement, that of the muon anomalous magnetic moment.
