【 摘 要 】

Rare leptonic decays of the B0(s), D and K mesons are sensitive probes of physics beyond the Standard Model. In particular, the search for the decays B0(s) → μ+μ-provides information on the presence of new (pseudo-)scalar particles. LHCb is well suited for these analyses due to its large acceptance for B-decays and trigger efficiency, as well as its excellent invariant mass resolution and electron and muon identification capabilities. Results on these searches using data collected by LHCb in 2011 and 2012 are presented.
