Search for New Physics in rare decays at LHCb

Understand

Rare heavy flavor decays provide stringent tests of the Standard Model of particle physics and allow to test for possible new Physics scenarios.

• The LHCb experiment at CERN is the ideal place for these searches as it has recorded the worlds largest sample of beauty mesons.
• The status of the rare decay analyses with 1\invfb of $\sqrt s = 7\tev $ of $pp$--collisions collected by the LHCb experiment in 2011 is reviewed.
• The worlds most precise measurements of the angular structure of \BdToKstmm decays is discussed, as well as the isospin asymmetry measurement in $\decay{B}{\kaon^{(*)} \mup\mun}$ decays.
