Search for \bar{B}^0 →Λ_c^+\bar{Λ}_c^- decay at Belle

Y. Uchida, H. Ozaki, H. Kichimi, I. Adachi et autres

We search for the doubly charmed baryonic decay \bar{B}^0 →Λ_c^+\bar{Λ}_c^-, in a data sample of 520×106 B\bar{B} events accumulated at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e^+e^- collider. We find no significant signal and set an upper …

Inclusive Measurement of the Photon Energy Spectrum in b→sγ Decays

P. Koppenburg, K. Abe, T. Abe, I. Adachi et autres

We report a fully inclusive measurement of the flavor changing neutral current decay b !s in the energy range 1:8 GeV E 2:8 GeV, covering 95% of the total spectrum.Using 140 fb ÿ1 , we obtain Bb !s 3:55 0:32 0:300:11 ÿ0:31ÿ0:07 …

Azimuthal asymmetries of back-to-back π± - (π0, η, π±) pairs in e+e- annihilation

H.Li, A.Vossen, H. Aihara, D.M. Asner et autres

This work reports the first observation of azimuthal asymmetries around the thrust axis in e þ e - annihilation of pairs of back-to-back charged pions in one hemisphere, and π 0 and η mesons in the opposite hemisphere.These results are complemented by …

First Observation of the Hadronic Transition Υ(4S) → ηhb(1P) and New Measurement of the hb(1P) and ηb(1S) Parameters

U.Tamponi, R.Mussa, A.Abdesselam, H. Aihara et autres

Using a sample of 771.6 × 10 6 ϒϒð4SÞ decays collected by the Belle experiment at the KEKB e þ e - collider, we observe, for the first time, the transition ϒð4SÞ → ηh b ð1PÞ with the branching fraction B½ϒð4SÞ → …
