The Higgs-boson lineshape

open access: yesNuclear Physics B, 2012
The current searches for a heavy Higgs boson assume on-shell (stable) Higgs-boson production. The Higgs-boson production cross section is then sampled with a Breit-Wigner distribution (with fixed-width or running-width) and implemented in MonteCarlo simulations.

Dilaton as the Higgs boson [PDF]

open access: yesThe European Physical Journal C, 2010
We propose a model where the role of the electroweak Higgs field is played by the dilaton. The model contains terms which explicitly violate gauge invariance, however it is shown that this violation is fictitious, so that the model is a consistent low energy effective theory. In the simplest version of the idea the resulting low energy effective theory

Composite Higgs Search at the LHC [PDF]

open access: yes, 2010
The Higgs boson production cross-sections and decay rates depend, within the Standard Model (SM), on a single unknown parameter, the Higgs mass.

Invisible Higgs Boson Decay into Massive Neutrinos of 4th Generation [PDF]

open access: yes, 2002
Results from several recent experiments provide inderect evidences in the favor of existence of a 4th generation neutrino. Such a neutrino of mass about 50 GeV is compatible with current physical and astrophysical constraints and well motivated in the ...

Search for a Higgs Boson Decaying to Weak Boson Pairs at LEP [PDF]

open access: yes, 2003
A Higgs particle produced in association with a Z boson and decaying into weak boson pairs is searched for in 336.4 1/pb of data collected by the L3 experiment at LEP at centre-of-mass energies from 200 to 209 GeV. Limits on the branching fraction of the

Search for invisible decays of a Higgs boson produced through vector boson fusion in proton-proton collisions at s=13TeV

open access: yesPhysics Letters B, 2019
A search for invisible decays of a Higgs boson is performed using proton-proton collision data collected with the CMS detector at the LHC in 2016 at a center-of-mass energy s=13TeV, corresponding to an integrated luminosity of 35.9fb−1.

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

On the Trail of the Higgs Boson [PDF]

open access: yesAnnalen der Physik, 2015
I review theoretical issues associated with the Higgs boson and the mystery of spontaneous breaking of the electroweak gauge symmetry. This essay is intended as an introduction to the special issue of Annalen der Physik, “Particle Physics after the Higgs”. image

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 ...
