New Theories for Physics beyond the Standard Model
The theoretical particle physics and cosmology group at Case Western Reserve University has a great tradition in this field of research. The PI is a new professor at CWRU, and his main goal is to establish a new theoretical effort in particle physics and cosmology. The PI has been working on physics beyond the Standard Model for more than 12 years and have published more than 75 publications in this field. The proposed research project will be crucial for the postdocs and students to understand the different theories for physics beyond the Standard Model and become world experts in this field of research. The main goal of this project is to investigate new theories for physics beyond the Standard Model. The Standard Model of Particle Physics is one of the most successful theories of nature, but it cannot explain many open issues in particle physics and cosmology. In this proposal we propose to investigate new ideas which could lead to a more complete theory. The PI has proposed new theories for physics beyond the Standard Model where the baryon and lepton numbers can be defined as local gauge symmetries spontaneously broken at the low scale. In these theories one can understand the proton stability and one have some interesting predictions for cosmology. These theories have the potential to change the standard paradigm for physics beyond the Standard Model, where one assumes a great desert between the electroweak scale and the scale where one has the possible unification of fundamental forces. In this context one does not need to postulate the great desert, the proton is stable, and one can have the unification of the gauge forces at the low scale. We propose to investigate theoretical, cosmological and phenomenological aspects of the theories where the baryon and lepton numbers are local gauge symmetries. We plan to investigate new possible baryogenesis mechanisms in the case where the local baryon number is spontaneously broken at the low scale. In this case there could be a relation between the baryon asymmetry and the asymmetry in the dark matter sector. In the context of these theories, one has different candidates for the cold dark matter in the Universe and we plan to investigate all predictions for direct detection experiments and the possible signals at gamma-ray telescopes. The different signatures at the Large Hadron Collider will be investigated in great detail. In these theories one predicts the existence of new particle with baryon and lepton numbers called lepto- baryons which can give rise to exotic signatures at the Large Hadron Collider. One of the most interesting aspects to study in this context is the unification of gauge forces. Since the proton is stable in this theory one can realized the unification at the low scale and understand the embedding of these theories in grand unified theories. These studies could define a new way to think about physics beyond the Standard Model.
