Abstract

A search for the B0s → D∗±D∓ decay is performed using proton-proton collisiondata at centre-of-mass energies of 7, 8 and 13 TeV collected by the LHCb experiment,corresponding to an integrated luminosity of 9 fb−1. The decay is observed with a highsignificance and its branching fraction relative to the B0 → D∗±D∓ decay is measured to beB(B0s → D∗±D∓)B(B0 → D∗±D∓)= 0.137 ± 0.017 ± 0.002 ± 0.006 ,where the first uncertainty is statistical, the second systematic and the third is due to theuncertainty on the ratio of the B0s and B0 hadronisation fractions.
