Le résumé fourni par la source

We report measurements for two-body charmless hadronic B decays with an η ′ meson in the final state. Using 11.1×10 6 B B ̄ pairs collected with the Belle detector, we find BF ( B + → η ′ K + )=(79 +12 −11 ±9)×10 −6 and BF ( B 0 → η ′ K 0 )=(55 +19 −16 ±8)×10 −6 , where the first and second errors are statistical and systematic, respectively. No signal is observed in the mode B + → η ′ π + , and we set a 90% confidence level upper limit of BF ( B + → η ′ π + )<7×10 −6 . The CP asymmetry in B ± → η ′ K ± decays is investigated and a limit at 90% confidence level of −0.20< A CP <0.32 is obtained.
