While the third-generation couplings of the Higgs boson have been observed and studied, the first and second-generation fermion couplings to the Higgs (except the Higgs-muon coupling) remain elusive. This is due to two reasons mostly: light quark Yukawas smallness, and the difficulty of tagging light quarks efficiently. Therefore, even at the High Luminosity LHC (HL- LHC), the projections for...
To fully characterize the Higgs boson, it is important to establish whether it presents coupling properties that are not expected in the Standard Model of particle physics. These can probe BSM effects, such as CP conserving or CP violating couplings to particles with masses not directly accessible at the LHC through virtual quantum loops. In this talk we will present the most recent searches...
Effective Field Theories provide an interesting way to parameterize indirect BSM physics, when its characteristic scale is larger than the one directly accessible at the LHC, for a large class of models. Even if the Higgs boson is SM-like, BSM effects can manifest itself through higher-dimension effective interactions between SM fields, providing indirect sensitivity through distortions of...
We present calculations of higher-order corrections for the production of a heavy charged-Higgs pair ($H^+H^−$) in the two-Higgs-doublet model at LHC energies. We calculate the NNLO soft-plus-virtual QCD corrections and the N$^3$LO soft-gluon corrections to the total cross section and the charged-Higgs rapidity distribution.
