Using a sample of 9.7 million B meson pairs collected with the CLEO detector, we study inclusive B meson decays to the chi_c1 and chi_c2 charmonia states. We measure the branching fraction for the inclusive chi_c1 production in B decays to…
In spite of the fact that the two-body $B$ decays into $\chi_{c2}$ such as $B \to \chi_{c2} K^{(*)}$ are suppressed by the QCD factorization effect, the inclusive $B \to \chi_{c2} X$ branching fraction amounts to one third of the…
