Title: Topics in heavy flavor decays and grand unified theories 
Author: Datta, Alakabha
Date: 1995
Abstract: This work consists of two parts. The first part deals with the study of decays of heavy flavor baryons (baryons containing one heavy quark). The form factors describing the decay of a heavy flavor baryon to a light baryon are studied in the heavy quark limit. The results for the form factors are used to calculate nonleptonic and semileptonic decays of the heavy flavor baryons. The second part of this work concerns the effects of Planck scale corrections (from higher dimensional gravity induced operators) on the low energy predictions of SO( 10) and the supersymmetric SU(5) grand unified theories. In particular we show that the Planck scale corrections can allow a low Left-Right symmetry scale MR ≈ TeV within a SO(10) grand unified theory which is consistent with precision measurements of the Standard model gauge coupling constants at LEP. In supersymmetric SU(5) we show that the effects of gravity induced dimension six operators can destroy the prediction of αs(Mz) unless the color triplet higgs mass is constrained to be below 7 x 10^16GeV.
