On light dilaton extensions of the Standard Model
(E D P Sciences, 2016-01-01)
We discuss the presence of a light dilaton in Conformal Field Theories deformed by a single scalar operator, in the holographic realization consisting of confining Renormalization Group flows. Then, we apply this formalism ...
Radiative Omega(-)->Xi(-)gamma decay and physics beyond the standard model
(World Scientific Publ Co Pte Ltd, 1997-01-01)
We investigate the impact of new physics beyond the Standard Model to the s --> d gamma process, which is responsible for the short-distance contribution to the radiative decay Omega-( )--> Xi(-) gamma. We study three ...
Flavor changing interaction models and strictly massless neutrinos
(Iop Publishing Ltd, 2000-01-01)
It is well known that experimental data, coming from solar and atmospheric neutrino detectors and also from experiments which look for neutrino oscillations. strongly suggest that neutrinos must have a mass different from ...
Double Higgs production at the LHC as a robust test of little Higgs models
We analyze double Higgs boson production at the LHC in the context of Little Higgs models. In double Higgs production, the diagrams involved are directly related to those that cause the cancellation of the quadratic ...
Reference Object Model For Database Systems Based On Set Theory

The Inert Doublet Model
Z(3) WIMP and SIMP Dark Matter from a Global U(1) Breaking
(Elsevier B.V., 2015-10-01)
We propose and study a scalar extension of the Standard Model which respects a Z(3) symmetry remnant of the spontaneous breaking of a global U(1)D-M symmetry. The model has a dark matter candidate whose relic density is ...
