With the discovery of the Higgs boson at the CERN Large Hadron Collider (LHC), the particle spectrum of the Standard Model (SM) is complete. The next target in high-energy physics is to rigorously test the SM and search for phenomena beyond it. The Higgs boson, a cornerstone of the SM, is essential for understanding the mechanism of electroweak symmetry breaking and is believed to be a gateway to new physics beyond the SM. Measuring the couplings of the Higgs boson to other elementary particles within the SM is crucial. While the couplings of the Higgs to the electroweak vector bosons and third-generation fermions have been measured and found consistent with SM predictions, the next objective is to determine the Yukawa couplings of the Higgs to the second-generation fermions. Alone this line, I will talk about two things: 1) the feasibility of probing the charm quark Yukawa coupling via Higgs decays to charmonia at the LHC. 2) the potential to determine the Higgs-muon interactions through multi-boson production processes at a multi-TeV muon collider.


Yang Ma is a postdoc fellow at INFN Bologna. He got his Ph.D. at the University of Pittsburgh in theoretical particle physics. He has been working on collider phenomenology, QCD, electroweak physics and Higgs physics.
