Light-quark Yukawa couplings from off-shell Higgs production

Journal of High Energy Physics, 2023
Yukawa couplings of the first quark generation are notoriously difficult to constrain due to their small values within the Standard Model. Here we propose Higgs off-shell production, with the Higgs boson decaying to four leptons, as a probe of the up ...

Effects of genuine dimension-six Higgs operators [PDF]

, 2003
We systematically discuss the consequences of genuine dimension-six Higgs operators. These operators are not subject to stringent constraints from electroweak precision data.

Unitarity bounds on extensions of Higgs sector

Journal of High Energy Physics, 2023
It is widely believed that extensions of the minimal Higgs sector is one of the promising directions for resolving many puzzles beyond the Standard Model (SM).

Disentangling Flavor Violation in the Top-Higgs Sector at the LHC [PDF]

, 2014
We study the LHC phenomenology of flavor changing Yukawa couplings between top quark, Higgs boson, and either an up or charm quark. Such $tuh$ or $tch$ couplings arise for instance in models in which Higgs sector is extended by the existence of ...

Probing anomalous Higgs couplings in H → ZV decays [PDF]

Modern Physics Letters A, 2017
We analyze the possibility of probing anomalous Higgs couplings in the rare decays H [Formula: see text] ZV, V being a vector quarkonium state. These rare decays involve both gauge as well as the Yukawa sectors and either of them can potentially be anomalous.
