Journal ArticleDOI

Observation of B+ ---> K(1)(1270)+ gamma

Heyoung Yang, +150 more
TL;DR: In this article, the authors report the observation of the radiative decay B+-->K1(1270)(+) gamma using a data sample of 140 fb(-1) taken at the Upsilon(4S) resonance with the Belle detector at the KEKB e+e-collider.

Measurement of Branching Fractions for B→ηcK(*) Decays

F. Fang, +190 more
TL;DR: In this article, the authors report measurements of branching fractions for charged and neutral $B\ensuremath{\rightarrow}{\ensuremath{\eta}}_{c}K$ decays where the meson is reconstructed in the neutral channel.
Journal ArticleDOI

Inclusive measurement of the photon energy spectrum in b → sγ decays

Patrick Koppenburg, +164 more
