The Higgs effective potential in the Littlest Higgs model at the one-loop level
Antonio Dobado, Lourdes Tabares-Cheluci, Siannah Penaranda
In this work we compute the contributions to the Higgs effective potential coming from the fermion and gauge boson sectors at the one-loop level in the context of the SU(5)/SO(5) L…
Catching photons from extra dimensions
J. A. R. Cembranos, A. Dobado, A. L. Maroto
In extra-dimensional brane-world models with low tension, brane excitations provide a natural WIMP candidate for dark matter. Taking into account the various constraints coming fro…
Some model-independent phenomenological consequences of flexible brane worlds
J. A. R. Cembranos, A. Dobado, A. L. Maroto
In this work we will review the main properties of brane-world models with low tension. Starting from very general principles, it is possible to obtain an effective action for the…
The ratio of viscosity to entropy density in a pion gas satisfies the KSS holographic bound
Antonio Dobado, Felipe J. Llanes-Estrada
We evaluate the ratio of shear viscosity to entropy density in a pion gas employing the Uehling-Uehlenbeck equation and experimental phase-shifts parameterized by means of the SU(2…
A f(R) gravity without cosmological constant
A. de la Cruz-Dombriz, A. Dobado
In this work we consider the possibility of describing the current evolution of the universe, without the introduction of any cosmological constant or dark energy (DE), by modifyin…
On the electroweak symmetry breaking in the Littlest Higgs model
Antonio Dobado, Lourdes Tabares, Siannah Penaranda
In the SU(5)/SO(5) little Higgs models radiative corrections give rise to the SU(2)_L x U(1)_Y symmetry breaking. In this work we start a program for a detailed determination of th…
