Masses of Quarks and Leptons in a Supersymmetric GUT
Abstract
The masses and their variation with energy of the elementary particles obtained by solving the one loop renormalization group equation (RGE) in the Minimal Supersymmetric Standard Model (MSSM) is considered. A mass about 115 GeV for all the fermions at GUT scale is found as the possible solution of RGE. The mass spectra of all the fermions are also obtained within acceptable errors. They are shown graphically to desend for the top quark but ascend for all other fermions from the laboratory to the GUT scale.
