LEP1 and SLC measurements provide accurate data for the process $e^+e^- \to f \bar f$
at a centre of mass energy~$s\sim M_Z^2$. This data is used to define various on
resonance pseudo observables, such as effective fermionic mixing angles, pole
asymmetries, partial and total $Z$~boson decay widths, peak cross sections, and
ratios of partial widths. Despite the fact that the experimental...

Indirect information about the possible scale of SUSY breaking is provided by
$B$-physics observables (BPO) as well as electroweak precision observables (EWPO). We
combine the constraints imposed by recent measurements of the BR(b -> s gamma),
BR(B_s -> mu mu),
BR(B_u -> tau nu_tau) and Delta M_B_s BPO with those obtained
from the experimental measurements of the MW, sin^2 theta_eff,...

In preparation for the LHC, it seems essential to constrain as much as
possible the new physics parameters. For this purpose, isospin asymmetry
in b to s gamma transitions appears as a very restricting observable to
explore the supersymmetric parameter space.

Already today, low-energy data from flavour physics experiments, high precision electroweak observables as well
as astrophysical data impose strong constraints on many new physics (NP) scenarios. In order to quantify the
agreement of a particular NP model with the existing experimental measurements, a consistent set of theory
predictions has to be provided. For that reason it is...

We present preliminary results from a survey of the ability of the ILC to distinguish
MSSM models which produce almost identical signals at the LHC. We have included a full
SM background sample and realistic detector simulation. Since the models we study are
chosen essentially at random from the low-energy MSSM parameter space, this is the
first such comprehensive survey unconstrained by...
