Rare Decays in LHCb

The LHCb detector has collected its first data at the collision energy of and is performing very well. With a focus on the Bs→μ+μ−, Bs→ϕγ and Bd→K⁎0μ+μ− decays, we explain why rare decays decays are important, demonstrate the validation of the detector we have done for them, and show our expected performance with the 2010 and 2011 data.
