Higgs inflation in minimal supersymmetric SU(5) GUT
Higgs inflation minimal supersymmetric
2011/10/14
The Standard Model Higgs boson with large non-minimal coupling to the gravitational curvature can drive cosmological inflation. We study this type of inflationary scenario in the context of supersymme...
Observational consequences of the Standard Model Higgs inflation variants

2011/10/10
We consider the possibility to observationally differentiate the Standard Model (SM) Higgs driven inflation with non-minimal couplingto gravity from other variants of SM Higgs inflation based on the s...

We consider a minimal scale-invariant extension of the Standard Model of particle physics combined with Unimodular Gravity formulated in \cite{Shaposhnikov:2008xb}. This theory is able to describe not...
We examine the neutralino dark matter phenomenology in supersymmetric scenarios with nonuniversal Higgs masses at the gauge coupling unification scale that can acommodate a light Higgs boson, where th...
We consider a simple extension of the Standard Model Higgs inflation with one new real scalar field which preserves unitarity up to the Planck scale. The new scalar field (called sigma) completes in ...
Spacetime Brout-Englert-Higgs effect in General Relativity interacting with p-brane matter
Brout-Englert-Higgs p-brane matter
2010/3/19
We review the manifestation of the Brout-Englert-Higgs effect in general relativity interacting with point-like and extended objects (p-branes including string for p=1 and membrane for p=2), which man...
