Title: Evidence of a New Narrow Resonance Decaying to χ c 1 γ in B χ c 1 γ K

Abstract

We report measurements of B χ c 1 γ K and χ c 2 γ K decays using 772 × 10 6 B B ¯ events collected at the Υ ( 4 S ) resonance with the Belle detector at the KEKB asymmetric-energy e + e - collider. Evidence of a new resonance in the χ c 1 γ final state is found with a statistical significance of 3.8 σ . This state has a mass of 3823.1 ± 1.8 ( stat ) ± 0.7 ( syst ) MeV / c 2 , a value that is consistent with theoretical expectations for the previously unseen 1 D 2 3 c c ¯ meson. We find no other narrow resonance and set upper limits on the branching fractions of the X ( 3872 ) χ c 1 γ and χ c 2 γ decays.
