The Higgs boson and cosmology [PDF]

open access: yesPhilos Trans A Math Phys Eng Sci, 2015
I will discuss how the Higgs field of the Standard Model may have played an important role in cosmology, leading to the homogeneity, isotropy and flatness of the Universe; producing the quantum fluctuations that seed structure formation; triggering the radiation-dominated era of the hot Big Bang; and contributing to the processes of baryogenesis and ...

Search for a CP-odd Higgs boson decaying to Zh in pp collisions at s=8 TeV with the ATLAS detector

open access: yesPhysics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 2015
A search for a heavy, CP-odd Higgs boson, A, decaying into a Z boson and a 125 GeV Higgs boson, h, with the ATLAS detector at the LHC is presented. The search uses proton–proton collision data at a centre-of-mass energy of 8 TeV corresponding to an ...

Angles on CP-violation in Higgs boson interactions

open access: yesPhysics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 2019
CP-violation in the Higgs sector remains a possible source of the baryon asymmetry of the universe. Recent differential measurements of signed angular distributions in Higgs boson production provide a general experimental probe of the CP structure of ...

Measurement and interpretation of differential cross sections for Higgs boson production at s=13TeV

open access: yesPhysics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 2019
Differential Higgs boson (H) production cross sections are sensitive probes for physics beyond the standard model. New physics may contribute in the gluon-gluon fusion loop, the dominant Higgs boson production mechanism at the LHC, and manifest itself ...

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 ...

Higgs boson as a dilaton [PDF]

open access: yesPhysics of Atomic Nuclei, 2010
We study possible phenomenological consequences of the recently proposed new approach to the Weinberg-Salam model. The electroweak theory is considered as a gravity and the Higgs particle is interpreted in it as a dilaton, without the usual potential of interaction in the Higgs sector. We have taken as a test the process of photons pair production, $e^+
