Angular analysis of B decaying into J/psi Tensor, J/psi Vector and J/psi Scalar

Abstract

The analysis of $B \to \jpsi K^{\star}_{2}(1430)$ decay mode is complicated by the fact that close to the $J^{PC}=2^{++}$ meson $\Kstart(1430)$, there lie other $J^{PC}=1^{--}$ and $J^{PC}=0^{++}$ resonances, $K^{\star }(1410)$ and $K_0^{\star }(1430)$ respectively. We show how an angular analysis can be used to isolate the contributions from the different resonances and partial waves contributing to the final state $B\to \jpsi K_X$, where $K_X$ could be any of the resonance $K_2^{\star }(1430)$, $K^{\star }(1410)$ or $K_0^{\star }(1430)$. For this purpose we study the time integrated differential decay rate. We also construct a time dependent angular asymmetry that enables a clean measurement of the mixing phase $\beta$ in the mode $B\to \jpsi \Kstart(1430)$ alone, without contributions from the decay modes $B\to\jpsi\Kstarsz(1430)$ or $B\to\jpsi\Kstar(1410)$.
