With the pp collision dataset collected at 13 TeV, detailed measurements of Higgs boson properties can be performed. The Higgs kinematic properties can be measured with increasing granularity, and interpreted to constrain beyond-the-Standard-Model phenomena. This talk presents the measurements of Higgs boson differential and fiducial cross sections with various decay modes, as well as their...

The study of the Higgs boson properties provides a unique window for the discovery of new physics at the LHC. New phenomena can in particular be revealed in the search for rare, lepton-flavor-violating or exotic decays of the Higgs boson, as well as in its possible couplings to hidden-sector states that do not interact under Standard Model gauge transformations. This talk presents recent...

There are two simple ways that the standard signals of the Standard Model Higgs boson can be depleted. Its couplings to fermions and gauge bosons can be suppressed by a universal factor, and part of its branching fraction can be drained into invisible final states. A large class of theories can impose one or both of these depletion factors, even if mild, by way of additional scalar bosons that...

The knowledge of the Higgs potential is crucial for understanding the origin of mass and thermal history of our universe. We show how collider measurements and observations of stochastic gravitational wave signals can complement each other to explore the multiform scalar potential in the 2HDM. Accounting for theoretical and current experimental constraints, we analyze the key ingredients in...

We present an analysis of Two Higgs Doublet Models with an extended flavor sector realizing Spontaneous Flavor Violation. In this framework, flavor changing neutral currents are suppressed by powers of CKM matrix elements and Yukawa insertions, allowing the New Physics states to be closer to the energy reach of current colliders. Breaking away from the New Physics paradigm that dictates...

This talk will cover recent measurements of Higgs boson decays to fermions, including H->cc, H->mumu and other rare modes, and measurements of the top-H coupling including CP measurements.

With the full Run 2 pp collision dataset collected at 13 TeV, very detailed measurements of Higgs boson properties and its interactions can be performed using its decays into bosons and fermions, shining light over the electroweak symmetry breaking mechanism. This talk presents the latest measurements of the Higgs boson properties by the ATLAS experiment in various decay channels, including...
