Effect of Anomalous Couplings on the Associated Production of a Single Top Quark and a Higgs Boson at the LHC [PDF]
, 2012 We consider the production of a single top quark in association with a Higgs boson at the LHC. In particular, we compute the cross sections for the processes $ p p \to t h j$, $t h b$, $t h W$, $t h j j$, $t h j b$, $t h W j$, $t h W b$ in the presence ...

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 ...

Anomalous Gauge Interactions of the Higgs Boson: Precision Constraints and Weak Boson Scatterings [PDF]
, 2002 Interaction of Higgs scalar (H) with weak gauge bosons (V=W,Z) is the {\it key} to understand electroweak symmetry breaking (EWSB) mechanism. New physics effects in the HVV interactions, as predicted by models of compositeness, supersymmetry and extra ...

Constraints on the Higgs boson anomalous FCNC interactions with light quarks
Nuclear Physics B, 2020 We consider the Higgs boson anomalous FCNC interactions with u, c, d, s and b quarks using the effective field theory framework. Constraints on anomalous couplings are derived from experimental results on Higgs boson production with subsequent decay into

Scaling and tuning of EW and Higgs observables [PDF]
, 2014 We study deformations of the SM via higher dimensional operators. In particular, we explicitly calculate the one-loop anomalous dimension matrix for 13 bosonic dimension-6 operators relevant for electroweak and Higgs physics.

Strong Higgs Interactions at a Linear Collider [PDF]
, 2013 We study the impact of Higgs precision measurements at a high-energy and high-luminosity linear electron positron collider, such as CLIC or the ILC, on the parameter space of a strongly interacting Higgs boson. Some combination of anomalous couplings are

Anomalous Higgs Couplings at the LHC
, 2011 We discuss the impact and potential discovery of physics beyond the Standard Model, coupling to the Higgs sector, at the LHC. Using a model-independent effective Lagrangian approach, pure Higgs and Higgs-gauge operators are analyzed, and their origin in terms of tree-level exchange of unknown heavy messengers is systematically derived.
