Higgs physics at CMS [PDF]

open access: yesEPJ Web of Conferences, 2019
The most recent results of a Higgs boson production and properties from the CMS Collaboration using the LHC Run 1 and Run 2 data are reported. These include analyses of a Higgs boson decaying to a pair of photons, four leptons via Z boson pair decays and

Measurements of Higgs boson production cross sections and couplings in the diphoton decay channel at s $$ \sqrt{\mathrm{s}} $$ = 13 TeV

open access: yesJournal of High Energy Physics, 2021
Measurements of Higgs boson production cross sections and couplings in events where the Higgs boson decays into a pair of photons are reported. Events are selected from a sample of proton-proton collisions at s $$ \sqrt{s} $$ = 13 TeV collected by the ...

The Higgs boson couplings: past, present, and future. The relationships between Higgs boson and other known particles as measured by current and future experiments

open access: yesFrontiers in Physics, 2023
The discovery of the Higgs boson, a fundamental particle of the Standard Model, at the Large Hadron Collider (LHC) in 2012, marked a monumental milestone in the field of particle physics.

The forgotten channels: charged Higgs boson decays to a W ± and a non-SM-like Higgs boson

open access: yesJournal of High Energy Physics, 2021
The presence of charged Higgs bosons is a generic prediction of multiplet extensions of the Standard Model (SM) Higgs sector. Focusing on the Two-Higgs-Doublet-Model (2HDM) with type I and lepton-specific Yukawa sectors, we discuss the charged Higgs ...

Measurements of Higgs boson production in the decay channel with a pair of $$\uptau $$ τ leptons in proton–proton collisions at $$\sqrt{s}=13$$ s = 13 TeV

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
Measurements of Higgs boson production, where the Higgs boson decays into a pair of $$\uptau $$ τ leptons, are presented, using a sample of proton-proton collisions collected with the CMS experiment at a center-of-mass energy of , corresponding to an ...

Associated Higgs boson production with Z boson in the minimal U(1)X extended Standard Model

open access: yesNuclear Physics B, 2023
The minimal U(1)X extension of the Standard Model (SM) is a simple and well-motivated extension of the SM, which supplements the SM with the seesaw mechanism for naturally generating the light neutrino masses and offers various interesting ...

Electroweak corrections to g + g → H l,h and H l,h → γ + γ in the Higgs-singlet extension of the Standard model

open access: yesJournal of High Energy Physics, 2023
We calculate the next-to-leading order electroweak corrections for Higgs-boson production in gluon fusion and the Higgs-boson decay into two photons or gluons in the real Higgs-singlet extension of the Standard model (HSESM). For the light Higgs-boson of

Probing Higgs-portal dark matter with vector-boson fusion

open access: yesJournal of High Energy Physics, 2020
We constrain the Higgs-portal model employing the vector-boson fusion channel at the LHC. In particular, we include the phenomenologically interesting parameter region near the Higgs resonance, where the Higgs-boson mass is close to the threshold for ...

Constraints on the Higgs boson self-coupling from single- and double-Higgs production with the ATLAS detector using pp collisions at s=13 TeV

open access: yesPhysics Letters B, 2023
Constraints on the Higgs boson self-coupling are set by combining double-Higgs boson analyses in the bb¯bb¯, bb¯τ+τ− and bb¯γγ decay channels with single-Higgs boson analyses targeting the γγ, ZZ⁎, WW⁎, τ+τ− and bb¯ decay channels. The data used in these

Probing extended Higgs sectors by the synergy between direct searches at the LHC and precision tests at future lepton colliders

open access: yesNuclear Physics B, 2021
We discuss a possibility that the parameter space of the two Higgs doublet model is significantly narrowed down by considering the synergy between direct searches for additional Higgs bosons at the LHC and its luminosity upgraded operation and precision ...
