If SUSY is realized at the TeV scale, it will likely be discovered at the LHC. After
discovery, it is crucial to gain information about SUSY Lagrangian parameters
from the measured observables with minimal prejudice. Fittino is a program
which performs a global fit of a defineable set of parameters to observables
accessible at the LHC and the ILC. We will give examples of such fits,...

The LHC provides us with new possibilities to test physics at the TeV scale and look
for signs of new physics beyond the Standard Model. If supersymmetry at the TeV scale
is realised in nature, LHC will be able to find many new particles and measure cross
sections and branching ratios which differ significantly from Standard Model
expectations. Then the question will arise: "What is the...

It used to be believed that SUSY breaking was difficult and required very special models with specific gauge groups and particle contents. I show that breaking SUSY and communicating it to the standard model can be done now with a wide variety of gauge groups and particle contents via gauge mediation. I will also discuss its implications on cosmology and collider searches.

Parallel Talk
We discuss two issues related to the precise determination
of the input parameters of the supersymmetric QCD. As a first
application we propose a consistent evaluation of $\alpha_s$ at the
GUT scale in the MSSM based on three-loop running and two-loop matching.
In the second part of the talk, the evaluation of the bottom
quark mass in the $\overline{\rm DR}$ scheme at the...

For MSSM phenomenology, soft SUSY-breaking dimension-three operators are important,
in particular the couplings between Higgs bosons and squarks. In scattering
processes, perturbative unitarity is violated at modest center-of-mass energy if
these couplings are much larger than the masses of the scalar particles involved.
Assuming perturbative unitarity, constraints on the trilinear...

We discuss the potential of combined analyses at LHC and ILC to explore
low-energy supersymmetry in a difficult region of the parameter space
characterized by masses of the scalar SUSY particles around 2 TeV. Precision
analyses of cross sections for light chargino production and
forward--backward asymmetries of decay leptons and hadrons at the ILC,
together with mass information on...
