Observation of the decay B0s to φπ+π- and evidence for B0 to φπ+π-

Abstract:

The first observation of the rare decay B0s to φπ+π- and evidence for B0 to φπ+π- are reported, using pp collision data recorded by the LHCb detector at centre-of-mass energies √s = 7 and 8 TeV, corresponding to an integrated luminosity of 3fb^-1. The branching fractions in the π+π- invariant mass range 400 < m(π+π-) < 1600 MeV/c2 are [3.48 ± 0.23 ± 0.17 ± 0.35] X 10^-6 and [1.82 ± 0.25 ± 0.41 ± 0.14] X 10^-7 for B0s to φπ+π- and B0 to φπ+π- respectively, where the uncertainties are sta...
