Probing Gauge-Mediated Supersymmetry Breaking Through Polarized Electron Beams in an Collider
Ambar Ghosal, Anirban Kundu, Biswarup Mukhopadhyaya
Using the facts that in Gauge-Mediated Supersymmetry Breaking schemes, masses of the right and the left sfermions can differ widely, and the gravitino is the Lightest Supersymmetri…
Some Implications of a Supersymmetric Model with R-Parity Breaking Bilinear Interactions
Sourov Roy, Biswarup Mukhopadhyaya
We investigate a supersymmetric scenario where R-parity is explicitly broken through a term bilinear in the lepton and Higgs superfields in the superpotential. We show that keeping…
A Non-perturbative Description of the Gimon-Polchinski Orientifold
Ashoke Sen
A T-dual version of the Gimon-Polchinski orientifold can be described by a configuration of intersecting Dirichlet seven branes and orientifold seven planes in the classical limit.…
Early Universe Evolution in Graviton-Dilaton Models
S. Kalyana Rama
We present a class of graviton-dilaton models which leads to a singularity free evolution of the universe. We study the evolution of a homogeneous isotropic universe. We follow an…
Vacuum structure and effective potential at finite temperature: a variational approach
Amruta Mishra, Hiranmaya Mishra
We compute the effective potential for theory with a squeezed coherent state type of construct for the ground state. The method essentially consists in optimising the basis a…
Non-commuting ETC corrections to zt\bar{t} vertex
Uma Mahanta
In this paper we calculate the corrections to zt\bar {t} couplings induced by non-commuting ETC interactions. The extra parameters \delgbl, s^2 and {1\over x} of non-commuting ETC…
