Journal ArticleDOI

Measurement of R and search for new quark flavors decaying into multi-jet final states in e + e - collisions between 54.0 and 61.4 GeV CM energies

TL;DR: In this article, a planar four-jet and other multi-jet events resulting from the decay of a charge were found to be possible, regardless of branching into charged current and loop-induced flavor-changing neutral current decay.
Journal ArticleDOI

Observation ofBs0→φγand Search forBs0→γγDecays at Belle

J. Wicht, +144 more
TL;DR: In this paper, the first radiative penguin decay was observed for the first time at the KEKB asymmetric energy collider, and a 90% confidence level upper bound was established.
Journal ArticleDOI

Study of time-dependent CP-violating asymmetries in b→sq̄q decays

Kazuo Abe, +191 more
- 01 Jan 2003 - 
TL;DR: In this paper, a measurement of CP-violation parameters in the b→sqq penguin transitions (q = s,u,d) based on a 78 fb-1 data sample collected at the Y(4S) resonance with the Belle detector at the KEKB energyasymmetric e+e- collider is presented.
Journal ArticleDOI

Measurement of the moments of the photon energy spectrum in B→Xsγ decays and determination of |Vcb| and mb at Belle

C. Schwanda, +135 more
- 27 Aug 2008 - 
TL;DR: In this article, the first and second moments of the spectrum for minimum photon energies in the B meson rest frame ranging from 1.8 to 2.3 GeV were determined using the previous Belle measurement of the inclusive photon energy in B→Xsγ decays.
Journal ArticleDOI

Measurement of CP violation in B0→D*-π+ and B0→D-π+ decays

F.J. Ronga, +159 more
- 01 May 2006 - 
TL;DR: In this paper, the authors obtained CP violation parameters S{sup +}(D{sup (*)}{pi}) and S {sup -}(d{sup*){pi}) from a data sample that contains 386x10{sup 6} BB pairs that was collected near the {upsilon}(4S) resonance, with the Belle detector at the KEKB asymmetric energy e{sup+}e{sup-} collider.
