TLDR
In this paper, the first observation of the charged B meson decay to chi(c0) and a charged kaon was made using a sample of 31.3x10(6) BB pairs collected with the Belle detector at the Upsilon(4S) resonance, where the measured branching fraction is B(B+-->chi(c 0)K+) = (6.0(+2.1)(-1.8)+/-1.1)x10(-4).
Abstract
Using a sample of 31.3x10(6) BB pairs collected with the Belle detector at the Upsilon(4S) resonance, we make the first observation of the charged B meson decay to chi(c0) and a charged kaon. The measured branching fraction is B(B+-->chi(c0)K+) = (6.0(+2.1)(-1.8)+/-1.1)x10(-4), where the first error is statistical, and the second is systematic.

Nonfactorizable contributions in B decays to charmonium: The case of B − → K − h c

TL;DR: In this article, the role of rescattering effects mediated by intermediate charmed meson production in non-leptonic B to charmonium decays was investigated, and an effective Lagrangian describing interactions of pairs of heavy-light $Q\overline{q} mesons with a quarkonium state was proposed.

B−→K−χc0 decay from charmed meson rescattering

TL;DR: In this paper, the authors study the process B−→K−χc0 considering intermediate charmed meson rescattering effects and find that rescattering effect is able to produce a large branching ratio consistent with measurements by Belle Collaboration.

Charmonium hybrid production in exclusive B-meson decays

TL;DR: In this article, the authors show that charmonium hybrid mesons with mass ∼4-GeV may be produced in B-decay via c c colour octet operators.

B→χcJK decays revisited

TL;DR: This article showed that exclusive B decays to P-wave charmonium factorize in the non-relativistic limit provided that colour-octet contributions are taken into account, and estimate the branching fractions.

Production of singletP-wavecc¯andbb¯states

TL;DR: In this paper, the authors discuss the production of the singlet P-wave quarkonium states using two possibilities: a single pion transition and a radiative transition.
