Our group has been working for more than 20 years on Theoretical Elementary Particle Physics. In particular, we have analyzed several aspects of the electroweak and strong interactions within the framework of the Standard Model (SM), as well as the phenomenological consequences of possible extensions of the SM. More recently, in the last few years we have incorporated building theories beyond the SM and studying their phenomenology, giving us a complete grasp of the process from basic theory all the way to experimental signals at various facilities, particularly the Large Hadron Collider (LHC) at CERN. The goal of this proposal is to obtain support to maintain our research projects which include the following three sub-areas: Extensions to the Standard Model: We shall study the properties and phenomenological consequences of extensions of the standard model, such as theories with strongly coupled electroweak sectors, extra dimensions or supersymmetry. We will build models that address several of the shortcomings of the SM, and consider the phenomenological consequences of these and other extensions of the standard model. We expect to concentrate on scenarios that are currently experimentally tested at facilities such as the LHC at CERN, which will be our guide for both model building and phenomenology. Collider physics: We will study many aspects of collider physics, focusing our efforts on the CERN Large Hadron Collider. For instance, we shall analyze the production and decay of new particles predicted by alternative models (e.g. super symmetric particles or Kaluza-Klein states) and study new interactions in the bosonic sector of the Standard Model using effective Lagrangians. Neutrino Physics: In neutrino physics we will continue to study ways to solve some of the remaining unknowns in the nature of neutrinos in the hope to be able to shed some light on the secrets of how the lepton sector is organized and on possible connections with the quark sector. We will also explore neutrino oscillation effects with current and future experimental data in order to probe new physics in the leptonic sector. (AU)
