Résumé

We report a first measurement of inclusive B→X_sη decays, where X_s is a charmless state with unit strangeness. The measurement is based on a pseudoinclusive reconstruction technique and uses a sample of 657×106BB̄ pairs accumulated with the Belle detector at the KEKB e⊃+e⊃- collider. For MX_s<2.6GeV/c₂, we measure a branching fraction of [26.1±3.0(stat)-2.1+1.9(syst)-7.1+4. 0(model)]×10^-5 and a direct CP asymmetry of AC _P=-0.13±0.04-0.03+0.02. Over half of the signal occurs in the range MX_s>1.8GeV/c₂.

N2 - We report a first measurement of inclusive B→Xsη decays, where Xs is a charmless state with unit strangeness. The measurement is based on a pseudoinclusive reconstruction technique and uses a sample of 657×106BB̄ pairs accumulated with the Belle detector at the KEKB e⊃+e⊃- collider. For MXs<2.6GeV/c2, we measure a branching fraction of [26.1±3.0(stat)-2.1+1.9(syst)-7.1+4. 0(model)]×10-5 and a direct CP asymmetry of AC P=-0.13±0.04-0.03+0.02. Over half of the signal occurs in the range MXs>1.8GeV/c2.
