Description
We search for the rare decays Bs to mu+mu- and D+ to pi+ mu+ mu- using a
large data set of proton-antiproton collisions recorded by the Dzero detector
operating at the Fermilab Tevatron Collider. These modes are expected to
have sizeable enhancements above the Standard Model rate due to new
physics. The Bs annihilation rate is expected to have orders of magnitude
enhancement in many models with large tan(beta) while the radiative charm
decays probe scenarios where sizeable new physics contributions are visible in
the up-sector quarks but not in the down-sector quarks. We present the most
stringent limits on both processes.
