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 ...

Higgs boson interactions in supersymmetric theories with large tan beta [PDF]

open access: yes, 1998
We show that radiative corrections to the Higgs potential in supersymmetric theories with large tan beta generically lead to large differences in the light Higgs boson decay branching fractions compared to those of the standard model Higgs boson.

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

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.

Gravitational Interaction of Higgs Boson and Weak Boson Scattering

open access: yes, 2013
With the LHC discovery of a 125 GeV Higgs-like boson, we study gravitational interaction of the Higgs boson via the unique dimension-4 operator involving Higgs doublet and scalar curvature, $\,\xi H^\dag H R\,$, with nonminimal coupling $\,\xi\,$.

Probing Charged Higgs Boson Couplings at the FCC-hh Collider

open access: yes, 2015
Many of the new physics models predicts a light Higgs boson similar to the Higgs boson of the Standard Model (SM) and also extra scalar bosons. Beyond the search channels for a SM Higgs boson, the future collider experiments will explore additional ...

LHC searches for the CP-odd Higgs by the jet substructure analysis

open access: yes, 2014
The LHC searches for the CP-odd Higgs boson is studied (with masses from 300 GeV to 1 TeV) in the context of the general two-Higgs-doublet model. With the discovery of the 125 GeV Higgs boson at the LHC, we highlight one promising discovery channel of ...

The CP-conserving two-Higgs-doublet model: the approach to the decoupling limit [PDF]

open access: yes, 2002
A CP-even neutral Higgs boson with Standard-Model-like couplings may be the lightest scalar of a two-Higgs-doublet model. We study the decoupling limit of the most general CP-conserving two-Higgs-doublet model, where the mass of the lightest Higgs scalar

Little Higgs Phenomenology

open access: yes, 2003
Recently a new class of models has emerged that addresses the naturalness problem of a light Higgs boson. In these ''little Higgs'' models, the Standard Model Higgs boson is a pseudo-Nambu-Goldstone boson of an approximate global symmetry.

New results for a photon-photon collider [PDF]

open access: yes, 2002
We present new results from studies in progress on physics at a two-photon collider. We report on the sensitivity to top squark parameters of MSSM Higgs boson production in two-photon collisions; Higgs boson decay to two photons; radion production in ...
