LEPTOGENESIS IN MODELS WITH MULTI-HIGGS BOSONS [PDF]

open access: yesModern Physics Letters A, 2002
We study the leptogenesis scenario in models with multi-Higgs doublets. It is pointed out that the washing-out process through the effective dimension-five interactions, which has not been taken into account seriously in the conventional scenario, can be effective, and the resultant baryon asymmetry can be exponentially suppressed.

Search for the neutral Higgs bosons of the minimal supersymmetric standard model in pp collisions at s√=7 TeV with the ATLAS detector [PDF]

open access: yes, 2012
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 ...

Nullification of multi-Higgs threshold amplitudes in the standard model [PDF]

open access: yesPhysics Letters B, 1993
We show that nullification of all tree-order threshold amplitudes involving Higgs particles in the Standard Model occurs, provided that certain equations relating the masses of all existing elementary particles to the mass of the Higgs scalar are satisfied.

The mass-degenerate SM-like Higgs and anomaly of (g − 2) μ in μ-term extended NMSSM

open access: yesJournal of High Energy Physics, 2022
We chose the μ-term extended next-to-minimal supersymmetric standard model (μNMSSM) for this work, and we perform a phenomenological study based on the assumption that the observed Standard Model (SM)-like Higgs is explained by the presence of a double ...

Pseudoscalar MSSM Higgs Production at NLO SUSY-QCD

open access: yesJournal of High Energy Physics, 2023
One of the most important mechanisms at the Large Hadron Collider (LHC) for the production of the pseudoscalar Higgs boson of the Minimal Supersymmetric Standard Model (MSSM) is the loop-induced gluon fusion process gg → A.

Higgs Boson Studies at the Tevatron [PDF]

open access: yes, 2013
We combine searches by the CDF and D0 Collaborations for the standard model Higgs boson with mass in the range 90--200 GeV$/c^2$ produced in the gluon-gluon fusion, $WH$, $ZH$, $t{\bar{t}}H$, and vector boson fusion processes, and decaying in the $H ...
