Abstract:
We report a search for B decays to selected final states with the η c meson: B ± → K ± η c π + π − , B ± → K ± η c ω , B ± → K ± η c η and B ± → K ± η c π 0 . The analysis is based on 772 × 10 6 B B ¯ BB¯¯¯ pairs collected at the Υ(4 S ) resonance with the Belle detector at the KEKB asymmetric-energy e + e − collider. We set 90% confidence level upper limits on the branching fractions of the studied B decay modes, independent of intermediate resonances, in the range (0 . 6–5 . 3) × 10 −4 . We also search for molecular-state candidates in the D 0 D ¯ ∗ 0 − D ¯ 0 D ∗ 0 , D 0 D ¯ 0 + D ¯ 0 D 0 D0D¯¯¯∗0−D¯¯¯0D∗0,D0D¯¯¯0+D¯¯¯0D0 and D ∗ 0 D ¯ ∗ 0 + D ¯ ∗ 0 D ∗ 0 D∗0D¯¯¯∗0+D¯¯¯∗0D∗0 combinations, neutral partners of the Z (3900) ± and Z (4020) ± , and a poorly understood state X (3915) as possible intermediate states in the d ... mehr
