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

open access: yes, 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 ...

Lepton number violation in Little Higgs model [PDF]

open access: yes, 2005
In this note we examine the constraints imposed by muon anomalous magnetic moment ($(g-2)_\mu$) and $\mu^- \to e^+ e^- e^-$ on lepton number violating (LNV) couplings of the triplet Higgs in Little Higgs (LH) model.Comment: revtex4.0 file, 5 pages ...

Anomalous Gauge Interactions of the Higgs Boson: Precision Constraints and Weak Boson Scatterings [PDF]

open access: yes, 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 ...

Scaling and tuning of EW and Higgs observables [PDF]

open access: yes, 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.

Constraints on the Higgs boson anomalous FCNC interactions with light quarks

open access: yesNuclear 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

High precision higgs from high energy muon colliders

open access: yesJournal of High Energy Physics, 2022
Muon colliders are an exciting possibility for reaching the highest energies possible on the shortest timescale. They potentially combine the greatest strengths of e + e − and pp colliders by bridging the energy versus precision dichotomy.

Gegenbauer’s Twin

open access: yesJournal of High Energy Physics, 2022
In Twin Higgs models the dominant source of fine-tuning is the cancellation of order v 2 /f 2 required to obtain a Standard Model-like Higgs, where v and f are the electroweak and new physics scales, respectively.

A perturbed lepton-specific two-Higgs-doublet model facing experimental hints for physics beyond the Standard Model

open access: yes, 2015
The BaBar, Belle, and LHCb collaborations have reported evidence for new physics in $B\to D\tau\nu$ and $B\to D^*\tau\nu$ of approximately $3.8\sigma$. There is also the long lasting discrepancy of about $3\sigma$ in the anomalous magnetic moment of the ...

Testing the Higgs boson gluonic couplings at LHC [PDF]

open access: yes, 1998
We study Higgs + jet production at hadron colliders in order to look for new physics residual effects possibly described by the $dim=6$ operators ${\O}_{GG}$ and ${\widetilde\O}_{GG}$ which induce anomalous $Hgg$ and $Hggg$ couplings.
