BSM patterns in scalar-sector coupling modifiers
Journal 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 ...

Gauge invariant accounts of the Higgs mechanism [PDF]
, 2011 The Higgs mechanism gives mass to Yang-Mills gauge bosons. According to the conventional wisdom, this happens through the spontaneous breaking of gauge symmetry.

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).

On the Impact of the LHC Run 2 Data on General Composite Higgs Scenarios
Advances in High Energy Physics, 2022 We study the impact of Run 2 LHC data on general composite Higgs scenarios, where nonlinear effects, mixing with additional scalars, and new fermionic degrees of freedom could simultaneously contribute to the modification of Higgs properties.

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 ...

On the study of the Higgs properties at a muon collider [PDF]
Modern Physics Letters A, 2015 The discovery of the Higgs particle at 125 GeV is demanding a detailed knowledge of the properties of this fundamental component of the Standard Model. To that aim various proposals of electron and muon colliders have been put forward for precision studies of the partial widths of the various decay channels.

Observation of a new particle in the search for the Standard Model Higgs boson at the CMS detector [PDF]
, 2013 The discovery of the Standard Model (SM) Higgs boson is one of the primary physics objectives of the Large Hadron Collider at CERN. This thesis describes a search carried out for the SM Higgs boson on data collected during the 2011 and 2012 proton ...

Analytic approximations of 2 → 2 processes with massive internal particles
Journal of High Energy Physics, 2023 We consider two-loop corrections to 2 → 2 scattering processes with massive particles in the final state and massive particles in the loop. We discuss the combination of analytic expansions in the high-energy limit and for small Mandelstam variable t ...

Higgs properties and fourth generation leptons
Physical Review D, 2011 It is possible that there are additional vector-like generations where the quarks have mass terms that do not originate from weak symmetry breaking, but the leptons only get mass through weak symmetry breaking. We discuss the impact that the new leptons have on Higgs boson decay branching ratios and on the range of allowed Higgs masses in such a model (

Search for the neutral Higgs bosons of the minimal supersymmetric standard model in pp collisions at s√=7 TeV with the ATLAS detector [PDF]
, 2013 A search for neutral Higgs bosons of the Minimal Supersymmetric Standard Model (MSSM) is reported. The analysis is based on a sample of proton-proton collisions at a centre-of-mass energy of 7 TeV recorded with the ATLAS detector at the Large Hadron ...
