Nonleptonic B dcays to radially excited charmless mesons
Summary
Nonleptonic two-body $B$ decays into radially excited mesons was studied using the framework of generalized naive factorization. We calculated branching ratios of $B\to P\pi^\prime$, $B\to V\pi^\prime$, $B\to P\rho^\prime$ and $B\to V\rho^\prime$, where $P$ and $V$ are pseudoscalar and vector charmless mesons, respectively. Form factors for $B\to \pi^\prime$ and $B\to \rho^\prime$ transitions were calculated in improved version of the Isgur-Scora-Grinstein-Wise quark model. Decay constants for $\pi^\prime$ and $\rho^\prime$ are estimated using light-cone quark model. In some processes branching ratios of $10^{-6}$ order were found, which could be reached in experiments.
