Ruiz Cembranos, José Alberto ; Dobado González, Antonio ; López Maroto, Antonio | IOP publishing ltd | 2007-06-22In this work, we will review the main properties of braneworld models with low tension. Starting from very general principles, it is possible to obtain an effective action for the relevant degrees of freedom at low energies (branons). Using the [...]![]()

Using the Fujikawa and the heat-kernel methods we make a complete and detailed computation of the global, gauge, and gravitational anomalies in the standard model defined on a curved space-time with torsion. We find new contributions coming from[...]![]()

This article presents a number of technical tools and results that may be instrumental to discern the nature of the Higgs particle. In scenarios where an additional strongly interacting sector is present in the electroweak theory, resulting in a[...]![]()

Delgado López, Rafael ; Dobado González, Antonio ; Llanes Estrada, Felipe José | American Institute of Physics (AIP) | 2016The apparent finding of a 125 GeV light Higgs boson would close the minimal Standard Model (SM), that is weakly interacting. This is an exceptional feature not generally true if new physics exists beyond the mass gap found at the LHC up to 700 G[...]![]()

Dobado González, Antonio ; Delgado López, Rafael ; Llanes Estrada, Felipe José | American Institute of Physics | 2014The apparent finding of a 125-GeV light Higgs boson closes unitarity of the minimal Standard Model (SM), that is weakly interacting: this is an exceptional feature not generally true if new physics exists beyond the mass gap found at the LHC up [...]![]()

Delgado López, Rafael ; Dobado González, Antonio ; Llanes Estrada, Felipe José | Elsevier Sciende BV | 2016-04Recently, a new boson h has been discovered at the LHC which, so far, is compatible with the properties of the SM Higgs. However, the SM is not the most general low-energy dynamics for the minimal electroweak symmetry breaking sector with three [...]![]()

If the symmetry-breaking sector of the standard model is strongly interacting, the low-energy dynamics of the longitudinal components of the weak bosons can be described by a nonlinear-sigma-model with two free parameters. For a large range of t[...]![]()

We study, within the recently proposed brane-world scenario, the effective action for the low-energy brane excitations. These modes are understood as Goldstone bosons associated to the spontaneous isometry breaking, induced on the bulk space by [...]![]()

In this work we derive the version of the Equivalence Theorem that applies when the symmetry breaking sector of the Standard Model is described by a general chiral lagrangian. The demonstration is valid for renormalized fields for any value of t[...]![]()

We study the heavy Higgs sector of the MSSM composed of the H+/-, H-0 and A(0) particles in the so-called decoupling limit where m(A0) > > m(z) By integrating out these heavy Higgs particles to one-loop, we compute the effective action for the [...]
