Abstract
The Standard Model (SM) of particle physics is an experimentally successful theory describing the strong, weak and electromagnetic forces. These forces are described by distinct interactions in the SM. Grand Unified Theories (GUTs) attempt to unify these forces into a single interaction. In this work we treat a GUT based on SO(10) with three intermediate symmetry scales between the GUT-scale and the SM. The coupling constants are shown to unify in such a scenario, for a range of intermediate energy scales. This model contains several leptoquarks, which are particles that have couplings with both a quark and a lepton. The model we discuss contains three leptoquarks below the GUT scale, a vector leptoquark U1, with SM representation (3,1,2/3) and two scalar leptoquarks R2 and `R2', with representations (3,2,7/6) and (3,2,1/6), respectively. The vector leptoquarks are experimentally restricted to lie at energies greater than 2 PeV. We describe a scenario with TeV-scale scalar leptoquarks. These leptoquarks mainly interact with the heaviest fermions (the third generation) and could potentially be observed at pp colliders.
