Abstract

The first dedicated search for the η_c2(1D) is carried out using the decays B⁺→ η_c2(1D)K⁺, B⁰ → η_c2(1D)KS0, B⁰→ η_c2(1D)π⁻K⁺, and B⁺→ η_c2(1D)π⁺KS0 with η_c2(1D) → h_cγ. No significant signal is found. For the η_c2(1D) mass range between 3795 and 3845 MeV/c², the branching-fraction upper limits are determined to be ℬ(B⁺→ η_c2(1D)K⁺) × ℬ(η_c2(1D) → h_cγ) < 3.7 × 10⁻⁵, ℬ(B⁰→ η_c2(1D)K⁰) × ℬ(η_c2(1D) → h_cγ) < 3.5 × 10⁻⁵, ℬ(B⁰→ η_c2(1D)π⁻K⁺) × ℬ(η_c2(1D) → h_cγ) < 1.0 × 10⁻⁴, and ℬ(B⁺→ η_c2(1D)π⁺KS0) × ℬ(η_c2(1D) → h_cγ) < 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.
