Angular analysis of $B^0\to D^{\ast -}{D}_s^{\ast +}$ with $D_s^{\ast +}\to D_s^{+}\gamma$ decays

LHCb collaboration, R. Aaij, C. Abellán Beteta +946

The first full angular analysis of the $B^0\to D^{\ast -}{D}_s^{\ast +}$ decay is performed using 6 fb${}^{-1}$ of $pp$ collision data collected with the LHCb experiment at a centre-of-mass…
