The Research program “Beyond the Standard Model: Theoretical Elementary Particle Physics and Cosmology under the light of LHC” aims to the study of central issues of Particle Physics and Cosmology in the framework of the Standard Model (SM) and its extensions. In particular, the problem of electroweak symmetry breaking, the role of the Higgs field, the SM extension that unifies interactions including gravitation, and the identification, construction and analysis of phenomenologically acceptable models.

These topics will be studied in the framework of the interrelated approaches of String Theory (ST), M-Theory, F-Theory, etc, with Supersymmetry playing a central role. The phenomenological predictions and the viability of these models will be analyzed in the light of existing data. Furthermore, central cosmological issues, as the problems of "œdark matter" and "œdark energy", will be addressed to in the framework of the above extensions. The proposed research aims at the following specific objectives:

  • Phenomenological analysis of the proposed extensions of the SM versus accelerator data for sparticles, the Higgs boson, "œdark matter" candidates, etc. Study of the phenomenological profile of electroweak symmetry breaking, flavor violation, etc. Development of computer algorithms for higher order processes.
  • Study of SM extensions based on ST, Branes, etc. Algorithmic search, consruction and analysis of phenomenological viability. Study of phenomenologically interesting observables (f.e. "anomalous" vector bosons) in the effective low energy theory.
  • Study of the QCD quark-gluon plasma through holographic techniques and computation of specific quantities (transport coefficients, etc).
  •  Study of mechanisms leading to an accelerated expansion of the Universe in general cosmologies. Study of the inflationary and “post-inflationary” periods and the primordial density perturbations.
  • Study of higher dimensional, low scale, black holes, analysis of their production processes in accelerator collisions and computation of the greybody factors of the emitted radiation.

Three research teams participate in the project:

  • Theoretical Physics group of University of Ioannina
  • Theoretical Physics group of University of Crete
  • Theoretical Physics group of University of Athens

The project budget amounts to 600.000 euros over three years. The coordinating institution is University of Ioannina and the scientific Coordinator is Prof. Kyriakos Tamvakis.
