We study the implications of non-universal boundary conditions for the composition
of the lightest neutralino as well as for the upper bound on its mass in
supersymmetric grand unified theories. We derive sum rules for neutralino and
chargino masses in different representations of the simplest grand unified theory
based on SU(5) which lead to different non-universal boundary conditions...

We propose a model of low scale gravity mediated supersymmetry breaking in
Randall-Sundrum type warped extra dimensions. In our setup, both of the visible
sector and the hidden sector (supersymmetry breaking sector) co-exist on infrared
(IR) brane. Supersymmetry breaking is transmitted through non-renormalizable contact
interactions among visible and hidden sector fields as the same as in...

In a R-parity violating (RPV) model of neutrino mass with three bilinear couplings
mu_i and three trilinear couplings lambda'_{i33}, where i is the lepton index, we
find six generic scenarios each with a distinctive pattern of the trilinear couplings
consistent with the oscillation data. These patterns may be reflected in direct RPV
decays of the lighter top squark or in the RPV decays of...

The precision determination of scalar top quark properties will play an important
role at a future International Linear Collider (ILC). The scenario with small
expected visible energies, from almost mass degenerate stops and neutralinos, is
cosmologically motivated and experimentally particularly challenging. This scenario
has been investigated with an Iterative Discriminant Analysis...

We present a study of various SUSY scenarios in which the lightest supersyummertric
particle (LSP) is the gravitino and the next-to-lightest supersymmetric particle
(NLSP) is a metastable stau with lifetimes ranging from seconds up to several years.
At the ILC such heavy stau's are copiously produced either directly or through
cascade decays. A proper choice of the cms energy allows one to...
