Study of $D_{s1}(2460{)}^{+}\to D_s^{+}{\pi }^{+}{\pi }^{-}$ in $B\to {\bar{D}}^{(\ast )}{D}_s^{+}{\pi }^{+}{\pi }^{-}$ decays

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1129

An amplitude analysis of the $D_{s1}(2460{)}^{+}\to D_s^{+}{\pi }^{+}{\pi }^{-}$ transition is performed simultaneously in $B^0\to D^{-}{D}_s^{+}{\pi }^{+}{\pi }^{-}$, $B^{+}\to{\bar{D}}^{0} D_{s}^{+}…
