Sphalerons in Two Higgs Doublet Theories [PDF]

open access: yes, 2001
We undertake a comprehensive investigation of the properties of the sphaleron in electroweak theories with two Higgs doublets. We do this in as model-independent a way as possible: by exploring the physical parameter space described by the masses and ...

BSM patterns in scalar-sector coupling modifiers

open access: yesJournal of High Energy Physics, 2023
We consider what multiple Higgs interactions may yet reveal about the scalar sector. We estimate the sensitivity of a Feynman topology-templated analysis of weak boson fusion Higgs pair production at present and future colliders — where the signal is a ...

Complementarity of LHC and EDMs for Exploring Higgs CP Violation [PDF]

open access: yes, 2015
We analyze the constraints on a CP-violating, flavor conserving, two Higgs doublet model from the measurements of Higgs properties and from the search for heavy Higgs bosons at LHC, and show that the stronger limits typically come from the heavy Higgs ...

New features in the JHU generator framework: Constraining Higgs boson properties from on-shell and off-shell production

open access: yes, 2020
We present an extension of the JHUGen and MELA framework, which includes an event generator and library for the matrix element analysis. It enables simulation, optimal discrimination, reweighting techniques, and analysis of a bosonic resonance and the ...

Composite Higgs Search at the LHC [PDF]

open access: yes, 2010
The Higgs boson production cross-sections and decay rates depend, within the Standard Model (SM), on a single unknown parameter, the Higgs mass.

Measurements of Higgs boson properties in the diphoton decay channel in proton-proton collisions at $\sqrt{s} =$ 13 TeV [PDF]

open access: yes, 2018
Measurements of Higgs boson properties in the H $\to\gamma\gamma$ decay channel are reported. The analysis is based on data collected by the CMS experiment in proton-proton collisions at $\sqrt{s} =$ 13 TeV during the 2016 LHC running period ...

Light-quark Yukawa couplings from off-shell Higgs production

open access: yesJournal 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 ...

Precise test of Higgs boson properties via triple Higgs boson production in vector boson fusion at future colliders [PDF]

open access: yesPhysical Review D, 2018
For certain classes of beyond the standard model theories, including composite Higgs models, the coupling of the Higgs to gauge bosons can be different from the standard model one. In this case, the multiboson production via vector boson fusion (VBF) can

Distinguishing a MSSM Higgs Boson from the SM Higgs Boson at a Linear Collider [PDF]

open access: yes, 2001
The decoupling properties of the Higgs sector in the Minimal Supersymmetric Standard Model (MSSM) imply that a light CP-even Higgs boson discovered at the Tevatron or LHC may closely resemble the Standard Model (SM) Higgs boson.
