Supersymmetric Grand Unification
  These lectures begin with a brief introduction to the minimal supersymmetric standard model (MSSM) and the various mechanisms for hidden sector supersymmetry breaking and go on to provide a pedagogical discussion of the various kinds of supersymmetric unified theories beyond the MSSM including SUSY GUTs. Their implications for proton decay, R-parity violation, doublet triplet splitting etc. are discussed. Exhaustive discussion of SU(5) and SO(10) models is given. Other GUT models such as those based on $E_6$, $SU(5)\times SU(5)$, flipped SU(5) and SU(6) are also presented.
