Abstract
The first observation of the rare decay Bs0→φπ+π- and evidence for B0→φπ+π- are reported, using pp collision data recorded by the LHCb detector at center-of-mass energies s=7 and 8 TeV, corresponding to an integrated luminosity of 3 fb-1. The branching fractions in the π+π- invariant mass range 400
