Observation of $B^0\to D^{\ast -}(5\pi {)}^{+}$, $B^{+}\to D^{\ast -}(4\pi {)}^{++}$ and $B^{+}\to {\bar{D}}^{\ast 0}(5\pi {)}^{+}$

G. Majumder

We report the first observation of a number of decay modes of the B meson, namely $B^0\to D^{\ast -}(5\pi {)}^{+}$, $B^{+}\to D^{\ast -}(4\pi {)}^{++}$ and $B^{+}\to {\bar{D}}^{\ast 0}(5\pi {)}^{+}$, where $(nπ)…
