We consider the role of extremely long lived charged massive particles in the
early Universe and discuss what we can learn if we discover such long lived
charged massive particle particles at future collider experiment.

Kination-dominated quintessence scenarios can provide an intriguing connection between thermal WIMP dark
matter and dark energy which can be tested at forthcoming and future colliders. We present the results of our
investigation of the implications of such nonstandard cosmological models for neutralino dark matter in the MSSM,
focusing on the role of the ILC in determining the...

We investigate the role of quantum corrections within the quintessence dark energy
scenario in the framework of low-energy effective field theory. In this framework,
the quintessence field, which can drive an accelerated cosmic expansion, is viewed as
arising from a high-energy theory, which is governed by a UV-scale of the order of
the GUT or Planck scales. We study the low-energy...

A new class of constraint system applicable to continuous covariant field theories is
explained. When coupled to gravity, it modifies the constraints of Einstein
equations. Cosmological implications are also presented.

We analyze the effect of variation of fundamental couplings and mass scales on
primordial nucleosynthesis in a systematic way. The first step establishes the
response of primordial element abundances to the variation of a large number of
nuclear physics parameters, including nuclear binding energies. We find a strong
influence of the $n-p$ mass difference (for the \hefo\ abundance), of the...

MSSM and SUSY GUTs are the candidates
of theoretical models beyond SM.
However the naive extensions of SM allow many arbitrary parameters
and many unobserved elementary (SUSY) particles, which
lose simplicity of Nature and the predictive powers.
In this talk, firstly we review quickly the NLSUSYGR
which describes the NLSUSY invariant coupling of
(Nambu-Godldstone...
