Cosmological implications of supersymmetric CP violating phases
We show that large SUSY phases have no significant effect on the relic
density of the lightest supersymmetric particle (LSP). However, they are very
significant for the detection rates. We emphasise that the phase of the
trilinear coupling increase the direct and indirect detection rates.Comment: 4 pages, 1 figure, talk given at Cosmo99, 27 Sept. - 2 Oct. 1999,

TeV Scale Gauged B-L With Inverse Seesaw Mechanism
We propose a modified version of the TeV scale B-L extension of the standard
model, where neutrino masses are generated through the inverse seesaw
mechanism. We show that heavy neutrinos associated with this model can be
accessible via clean signals at the LHC. The search for the extra gauge boson
Z'_{B-L} through the decay into dileptons or two dileptons plus missing energy
is studied. We also show that the B-L extra Higgs can be directly probed at the
LHC via a clean dilepton and missing energy signal.Comment: 4 pages, revte
Cosmological Consequences of QCD Phase Transition(s) in Early Universe
We discuss the cosmological consequences of QCD phase transition(s) on the
early universe. We argue that our recent knowledge about the transport
properties of quark-gluon plasma (QGP) should throw additional lights on the
actual time evolution of our universe. Understanding the nature of QCD phase
transition(s), which can be studied in lattice gauge theory and verified in
heavy ion experiments, provides an explanation for cosmological phenomenon stem
from early universe.Comment: 8 pages, 2 eps figure
Stability in Generalized Modified Gravity
The stability issue of a large class of modified gravitational models is
discussed with particular emphasis to de Sitter solutions. Three approaches are
briefly presented and the generalization to more general cases is mentioned.Comment: 6 pages, talk delivered at DSU08 Cair
