Abstract
The first observation of the decay View the MathML source and a study of B0→χc1,2K∗0 decays are presented. The analysis is performed using a dataset, corresponding to an integrated luminosity of 1.0 fb−1, collected by the LHCb experiment in pp collisions at a centre-of-mass energy of 7 TeV. The following ratios of branching fractions are measured:
B(B0s→χc1φ)/B(B0s→J/ψφ) = (18.9±1.8 (stat) ±1.3 (syst) ±0.8(B))×10−2,
B(B0→χc1K∗0)/B(B0→J/ψK∗0)
=
(19.8±1.1 (stat) ±1.2 (syst) ±0.9(B))
×10−2,
B(B0→χc2K∗0)/B(B0→χc1K∗0)
=
(17.1 ±5.0 (stat)±1.7 (syst)±1.1(B))
×10−2,
where the third uncertainty is due to the limited knowledge of the branching fractions of χc→J/ψγ
