Journal ArticleDOI

A search for excited electrons in the e+e− reactions up to the √s of 56 GeV

TL;DR: In this paper, a lower limit for the mass of excited electrons, e ∗' s, has been obtained by making use of the processes e + e − →e + e− γγ and e − γ ( e ) (quasi-real Compton scattering).
Journal ArticleDOI

Measurement of the direct CP asymmetry in B ¯ →xs+dγ decays with a lepton tag

L. Pesántez, +185 more
TL;DR: In this article, the authors reported the measurement of the direct CP asymmetry in the radiative (B) over bar -> Xs+d gamma decay using a data sample of (772 +/- 11) x 10(6) B (B), over bar pairs collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric energy e(+)e(-) collider.
Journal ArticleDOI

Measurement of time-dependent CP violation in B0 → KS0π0π0 decays

Y. Yusa, +172 more
- 18 Jan 2019 - 
TL;DR: In this paper, a measurement of time-dependent CP violation in B0→KS 0π0π0 decays using a data sample of 772×106 BB¯ pairs collected by the Belle experiment running at the ϒ(4S) resonance at the KEKB e+e- collider was reported.
Journal ArticleDOI

Observation of B+ --> Lambda c+ Lambda c- K+ and B0 --> Lambda c+ Lambda c- K0 decays.

N. Gabyshev, +128 more
TL;DR: The first measurements of the doubly charmed baryonic B decays were reported in this article, where a branching fraction of (65{sub -09}{sup +10+-10++-12{+-}41)x10{sup -4} and a statistical significance of 66{sigma were obtained.
Journal ArticleDOI

Measurement of τ polarization in e+e- annihilation at √s = 58 GeV

TL;DR: In this article, the average polarization of τ leptons in the reaction e+e− → τ+τ− has been measured using a TRISTAN at the center-of-mass energy of 58 GeV.
