Query: New minimal supersymmetric SO(10) GUT phenomenology and its cosmological
  implications   Supersymmetric GUTs based on SO(10) gauge group are leading contenders to
describe particle physics beyond the Standard Model. Among these the "New
minimal supersymmetric SO(10) grand unified theory" (NMSGUT) based on Higgs
system 10+120+210+126+$\overline{126}$ has been developing since 1982. It now
successfully fits the whole standard Model gauge coupling, symmetry breaking
and fermion mass-mixing data as well as the neutrino mass and mixing data in
terms of NMSGUT parameters and just 6 soft supersymmetry breaking parameters
defined at the GUT scale. In this thesis we study the phenomenology of NMSGUT,
its implications for inflationary and Cold Dark matter cosmology and develop
Renormalization group(RG) equations for the flow of NMSGUT couplings in the
extreme ultraviolet. In the first part we show that superheavy threshold
effects can drastically lower the SO(10) yukawa couplings required for
realistic unification and this cures the long standing problem of fast proton
decay in Susy GUT. Then we propose a novel Supersymmetric Seesaw
inflection(SSI) scenario based upon a SU(2)_L x U(1)_R x U(1)_{B-L} invariant
model, where the inflation mass is controlled by the large conjugate sneutrino
mass. We show that it is much less fine-tuned and more stable than Dirac
sneutrino based MSSM inflation. NMSGUT can embed SSI, and even provide a large
tensor scalar ratio, but obstacles in achieving enough inflation remain. The
NMSGUT Bino LSP is a good dark matter candidate when it can co-annihilate with
a nearly degenerate sfermion as in fits with a light smuon. We also calculate
two loop NMSGUT gauge-Yukawa Renormalization Group(RG) beta functions and show
that GUT scale negative Higgs mass squared parameters required by NMSGUT fits
can arise by RG flows from positive values at the Planck scale.
