Exploring Complex Phases of the MSSM at Future Colliders
Once Supersymmetry is discovered, exploring the phases of supersymmetric
parameters will be one of the most important tasks of future colliders. We
analyze the possibilities of investigating the phases of the cMSSM via their
effects on the Higgs sector through radiative corrections. Within two benchmark
scenarios we compare the capabilities of the LHC, the ILC and a future gamma
gamma collider.Comment: 6 pages, 10 figures. Talk given by S. Heinemeyer at the 2005

Study of semileptonic and nonleptonic decays of the meson
We evaluate semileptonic and two--meson nonleptonic decays of the
meson in the framework of a nonrelativistic quark model. The former are done in
spectator approximation using one--body current operators at the quark level.
Our model reproduces the constraints of heavy quark spin symmetry obtained in
the limit of infinite heavy quark mass. For the two--meson nonleptonic decays
we work in factorization approximation. We compare our results to the ones
obtained in different relativistic approaches.Comment: Talk given at the IVth International Conference on Quarks an Nuclear
