First observation of the rare đ”+ â đ·+ đŸ+ Ïâ decay
- Abstract:
- The B+âD+K+Ï- decay is observed in a data sample corresponding to 3.0 fb-1 of pp collision data recorded by the LHCb experiment during 2011 and 2012. The signal significance is 8Ï and the branching fraction is measured to be B(B+âD+K+Ï-)=(5.31±0.90±0.48±0.35)Ă10-6, where the uncertainties are statistical, systematic and due to the normalization mode B+âD-K+Ï+, respectively. The Dalitz plot appears to be dominated by broad structures. Angular distributions are exploited to search for quasi-two-body contributions from B+âD2â(2460)0K+ and B+âD+Kâ(892)0 decays. No significant signals are observed and upper limits are set on their branching fractions.
