Natural NMSSM Higgs bosons

open access: yesNuclear Physics B, 2013
We study the phenomenology of Higgs bosons close to 126 GeV within the scale invariant unconstrained next-to-minimal supersymmetric Standard Model (NMSSM), focusing on the regions of parameter space favoured by low fine-tuning considerations, namely stop masses of order 400 GeV to 1 TeV and an effective $μ$ parameter between 100-200 GeV, with large ...

Mounting evidence for a 95 GeV Higgs boson

open access: yesJournal of High Energy Physics, 2022
In 2018 CMS reported an excess in the light Higgs-boson search in the diphoton decay mode at about 95 GeV based on Run 1 and first year Run 2 data. The combined local significance of the excess was 2.8 σ. The excess is compatible with the limits obtained

Standard model and predictions for the Higgs boson

open access: yesPhysical Sciences and Technology, 2022
This article describes the electroweak interactions of the Standard Model (SM) with Brout-Englert-Higgs (BEH) mechanism, the appearance and properties of the Higgs boson.

Measurements of Higgs-boson decays to leptons with the ATLAS detector

open access: yesSciPost Physics Proceedings, 2019
Since its discovery in 2012, the Higgs boson has served as an important probe for precision measurements of the Standard Model and for searches for new physics beyond the Standard Model.

The 7% rule: A maximum entropy prediction on new decays of the Higgs boson

open access: yesNuclear Physics B, 2020
The entropy of the Higgs boson decay probabilities distribution in the Standard Model (SM) is maximized for a Higgs mass value that is less than one standard deviation away from the current experimental measurement.

Signal-background interference effects in Higgs-mediated diphoton production beyond NLO

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
In this paper we consider signal-background interference effects in Higgs-mediated diphoton production at the LHC. After reviewing earlier works that show how to use these effects to constrain the Higgs boson total decay width, we provide predictions ...

Non-factorizable virtual corrections to Higgs boson production in weak boson fusion beyond the eikonal approximation

open access: yesJournal of High Energy Physics, 2023
Non-factorizable virtual corrections to Higgs boson production in weak boson fusion at next-to-next-to-leading order in QCD were estimated in the eikonal approximation [1]. This approximation corresponds to the expansion of relevant amplitudes around the

Status of the charged Higgs boson in two Higgs doublet models

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
The existence of charged Higgs boson(s) is inevitable in models with two (or more) Higgs doublets. Hence, their discovery would constitute unambiguous evidence for new physics beyond the Standard Model (SM).

Beyond-the-Standard Model Higgs Physics using the ATLAS Experiment

open access: yesEPJ Web of Conferences, 2016
Recent searches for the Higgs boson in the context of beyond the Standard Model performed by the ATLAS experiment are presented: high mass Higgs boson searches, lepton flavour violating Higgs decay, NMSSM, constraint from the search for three photons ...

Measurements of properties of the Higgs boson decaying to a W boson pair in pp collisions at s=13TeV

open access: yesPhysics Letters B, 2019
Measurements of the production of the standard model Higgs boson decaying to a W boson pair are reported. The W+W− candidates are selected in events with an oppositely charged lepton pair, large missing transverse momentum, and various numbers of jets ...
