Abstract

The standard model of particle physics is expected to be an incomplete description. For instance, it provides no natural explanations for the observed baryon asymmetry and the hierarchy problem. Possible extensions of the standard model are grand unified theories (GUTs). Many GUTs predict the existence of leptoquarks: hypothetical particles that directly couple quarks to leptons. This thesis discusses the possible mass scales of leptoquarks in GUTs based on the groups SU(5), SO(10) and SU(3)_C ×SU(3)_L×SU(3)_R (trinification). Among the theories that we have considered in this thesis, the model with the lowest leptoquark masses is an SO(10) GUT with three intermediate symmetry scales. In this scenario, TeV-scale vector leptoquarks are naturally possible. As far as we are aware, such a scenario has not been explored yet in any existing literature.
