Higgs properties and fourth generation leptons [PDF]

open access: yesPhysical Review D, 2011
It is possible that there are additional vector-like generations where the quarks have mass terms that do not originate from weak symmetry breaking, but the leptons only get mass through weak symmetry breaking. We discuss the impact that the new leptons have on Higgs boson decay branching ratios and on the range of allowed Higgs masses in such a model (

Electroweak Baryogenesis and Higgs Properties [PDF]

open access: yes, 2012
We explore the connection between the strength of the electroweak phase transition and the properties of the Higgs boson. Our interest is in regions of parameter space that can realize electroweak baryogenesis. We do so in a simplified framework in which a single Higgs field couples to new scalar fields charged under SU(3){sub c} by way of the Higgs ...

SM Higgs properties measurement at ATLAS [PDF]

open access: yesAIP Conference Proceedings, 2010
The discovery of a new particle in the Higgs searches being prepared for LHC will not guarantee that the Standard Model Higgs boson has been seen. This paper discusses the possibilities for measuring the spin, parity and couplings of the particle, under the assumption that it does in fact behave like the Standard Model Higgs.

On the study of the Higgs properties at a muon collider [PDF]

open access: yesCoherent States in Gauge Theories and Applications in Collider Physics, 2015
The discovery of the Higgs particle at 125 GeV is demanding a detailed knowledge of the properties of this fundamental component of the Standard Model.

Observation of the diphoton decay of the Higgs boson and measurement of its properties [PDF]

open access: diamondEuropean Physical Journal C: Particles and Fields, 2014
Observation of the diphoton decay mode of the recently discovered Higgs boson and measurement of some of its properties are reported. The analysis uses the entire dataset collected by the CMS experiment in proton-proton collisions during the 2011 and ...
