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 ...

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 ...

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 ...

Measurements of properties of the Higgs boson decaying into the four-lepton final state in pp collisions at s=13$$ \sqrt{s}=13 $$ TeV [PDF]

open access: yes, 2017
A bstractProperties of the Higgs boson are measured in the H → ZZ → 4ℓ (ℓ = e, μ) decay channel. A data sample of proton-proton collisions at s=13$$ \sqrt{s}=13 $$ TeV, collected with the CMS detector at the LHC and corresponding to an integrated ...

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 ...

CP Properties of Higgs Boson Interactions with Top Quarks in the (tt)over-barH and tH Processes Using H -g gamma gamma with the ATLAS Detector

open access: yes, 2020
A study of the charge conjugation and parity (CP) properties of the interaction between the Higgs boson and top quarks is presented.

The CP-conserving two-Higgs-doublet model: the approach to the decoupling limit [PDF]

open access: yes, 2002
A CP-even neutral Higgs boson with Standard-Model-like couplings may be the lightest scalar of a two-Higgs-doublet model. We study the decoupling limit of the most general CP-conserving two-Higgs-doublet model, where the mass of the lightest Higgs scalar

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 ...

Two-loop infrared singularities in the production of a Higgs boson associated with a top-quark pair

open access: yesJournal of High Energy Physics, 2022
The associated production of a Higgs boson and a top-quark pair is important for probing the Yukawa coupling of the top quark, and calls for better theoretical modeling.
