Colliders - Susy Phenomenology
Parallel Talk
We have performed detailed analysis of the SUSY focus point (FP) region
and work out new set of kinematical variables and cuts
which significantly extend LHC reach in FP
region compared to previoius results.
This opens new perspectives
for the SUSY searches at the LHC in FP the related fate of the ILC.

Colliders - Susy Phenomenology
Parallel Talk
We study a supersymmetric scenario where the lighter tau-sneutrino is the lightest
supersymmetric particle, while the lighter stau-state is the next lightest. Such a
scenario can be motivated within the framework of minimal supergravity, with just the
addition of a right-chiral neutrino superfield. Such a spectrum leads to rather
unusual signals of supersymmetry, showing stable tracks of...

Colliders - Susy Phenomenology
Parallel Talk
Many supersymmetric models predict many new particles within the reach of the
next generation of colliders. For an understanding of the model structure and the
mechanism(s) of symmetry breaking, it is important to know the masses of the new
particles precisely. The measurement of the mass of the scalar partner
of the top quark (stop) at an e+e- collider is studied. A relatively light stop...

Colliders - Susy Phenomenology
Parallel Talk
A study of various SUSY scenarios is presented in which the lightest supersymmetric
particle is the gravitino $\sG$ and the next-to-lightest supersymmetric particle is a
scalar tau $\stau$ with lifetimes ranging from seconds to years. Gravitinos are
interesting dark matter candidates which can be produced in decays of heavier
sparticles at the International Linear Collider (ILC), but...

Colliders - Susy Phenomenology
Parallel Talk
The spin of supersymmetric particles can be determined at e+e- colliders
unambiguously without any model assumptions. This will be demonstrated
for sleptons and charginos/neutralinos, based on the analysis of excitation
curves and angular distributions in production and decay processes. In
this way supersymmetry can be discriminated from theories with isomorphic
particle spectra...
