Strength of the trilinear Higgs boson coupling in technicolor models
(Elsevier B.V., 2006-10-05)
We discuss the strength of the trilinear Higgs boson coupling in technicolor (or composite) models in a model independent way. The coupling is determined as a function of a very general ansatz for the technicolor self-energy, ...
Hidden sector effects on double Higgs production near threshold at the LHC
(Elsevier B.V., 2011-08-19)
In this Letter we study a novel effect of a hidden sector coupling to the standard model Higgs boson: an enhancement of the Higgs pair production cross section near threshold due to bound state effects. After summing the ...
Production of the mssm higgs bosons at next generation linear e+ e- colliders

Multiple higgs and vector boson production beyond the standard model
If the electroweak symmetry breaking is originated from a strongly coupled sector, as for instance in composite Higgs models, the Higgs boson couplings can deviate from their Standard Model values. In such cases, at ...
Constraining anomalous Higgs boson interactions
(AMER PHYSICAL SOCCOLLEGE PK, 2012)
The recently announced Higgs boson discovery marks the dawn of the direct probing of the electroweak symmetry breaking sector. Sorting out the dynamics responsible for electroweak symmetry breaking now requires probing the ...
Robust CERN LHC Higgs boson search in weak boson fusion
(American Physical Soc, 2004-04-01)
We demonstrate that a CERN LHC Higgs boson search in weak boson fusion production with subsequent decay to weak boson pairs is robust against extensions of the standard model or minimal supersymmetric standard model involving ...
Searching for an invisibly decaying Higgs boson in e+e-, eγ, and γγ collisions
(Elsevier B.V., 1994-12-01)
Higgs bosons can have a substantial invisible branching ratio in many extensions of the Standard Model, such as models where the Higgs bosons decay predominantly into light or massless weakly interacting Goldstone bosons. ...
Soft-gluon resummation for pseudoscalar Higgs boson production at hadron colliders
(Elsevier Science, 2008-01)
We compute the threshold-resummed cross section for pseudo-scalar MSSM Higgs boson production by gluon fusion at hadron colliders. The calculation is performed at next-to-next-to leading logarithmic accuracy. We present ...
THE HIGGS PORTAL and AN UNIFIED MODEL FOR DARK ENERGY and DARK MATTER
(World Scientific Publ Co Pte Ltd, 2008-12-10)
We examine a scenario where the Higgs boson is coupled to an additional Standard Model singlet scalar field from a hidden sector. We show that, in the case where this field is very light and has already relaxed to its ...
