| dc.description.abstract | The first dedicated search for the ηc2(1D) is carried out using the decays B+→ ηc2(1D)K+, B0 → ηc2(1D)K0S, B0→ ηc2(1D)π−K+, and B+→ ηc2(1D)π+K0S with ηc2(1D) → hcγ. No significant signal is found. For the ηc2(1D) mass range between 3795 and 3845 MeV/c2, the branching-fraction upper limits are determined to be ℬ(B+→ ηc2(1D)K+) × ℬ(ηc2(1D) → hcγ) < 3.7 × 10−5, ℬ(B0→ ηc2(1D)K0) × ℬ(ηc2(1D) → hcγ) < 3.5 × 10−5, ℬ(B0→ ηc2(1D)π−K+) × ℬ(ηc2(1D) → hcγ) < 1.0 × 10−4, and ℬ(B+→ ηc2(1D)π+K0S) × ℬ(ηc2(1D) → hcγ) < 1.1 × 10−4 at 90% C.L. The analysis is based on the 711 fb−1 data sample collected on the ϒ(4S) resonance by the Belle detector, which operated at the KEKB asymmetric-energy e+e− collider. | es_ES |
