A measurement of inclusive and differential fiducial cross-sections for the production of the Higgs boson decaying to two photons is performed using 139 fb−1 of proton–proton collision data recorded at √s = 13 TeV by the ATLAS experiment at the Large Hadron Collider. The inclusive cross-section times branching ratio, in a fiducial region closely matching the experimental selection, is measured...

Multiple EW vector boson amplitudes are known to have bad energy behavior for individual Feynman diagrams, which causes many problems for numerical and theoretical analysis. Based on Goldstone equivalence theorem(GET), we introduce a new representation of Feynman rules that makes GET manifest, while reproduces the exact results of the amplitudes. The new helicity has no subtle gauge...

The CP property of the 125 GeV Higgs boson remains a mystery nowadays, which implies the possibility of new physics. We consider a scenario that degenerated 125 GeV CP-even and CP-odd Higgs bosons in a CP conserving Lagrangian will contribute to nontrivial CP measurement. We use 2HDM as an example to show that DiHiggs production in future hadron and electron-positron colliders are potentially...

This talk will present a measurement of the charge conjugation and parity ($CP$) properties in the Higgs boson interaction with $\tau$ leptons. The Yukawa interaction is generalized with a single mixing angle parameter $\phi_{\tau}$ to describe $CP$-odd interactions between the Higgs boson and $\tau$ leptons. The study is based on a measurement of $CP$-sensitive angular observables defined by...

The Higgs boson couplings to fermions and vector bosons have been well established since its discovery. Measuring the Higgs interaction with the charm quark is one of the next milestones on LHC, yet it is a challenging task due to the small branching ratio of H→cc̅ and the difficulty in charm tagging. This talk presents the latest search for a Higgs boson decaying to a cc̅ pair using the VH...

We calculate the decay branching fractions of the Higgs boson to $J/\psi$ and $\eta_c$ via the charm-quark fragmentation mechanism for the color-singlet and color-octet states in the framework of non-relativistic QCD.
The decay rates are governed by the charm-quark Yukawa coupling, unlike the decay $H\to J/\psi + \gamma$, which is dominated by the $\gamma^*$-$J/\psi$ mixing.
We find that...
