“…We use the full ϒð4SÞ data sample containing 772 × 10 6 BB pairs recorded with the Belle detector [42] at the asymmetric-beam-energy e þ e − collider KEKB [43]. The Belle detector is a large-solid-angle magnetic spectrometer that consists of a silicon vertex detector (SVD), a 50-layer central drift chamber (CDC), an array of aerogel threshold Cherenkov counters (ACC), a barrel-like arrangement of time-of-flight scintillation counters (TOF) and an electromagnetic calorimeter (ECL) comprised of CsI(Tl) crystals located inside a superconducting solenoid coil that provides a 1.5 T magnetic field.…”

We report a measurement of the cross section for K 0 S pair production in single-tag two-photon collisions,GeV 2 , where Q 2 is the negative of the invariant mass squared of the tagged photon. The measurement covers the kinematic range 1.0 GeV < W < 2.6 GeV and j cos θ Ã j < 1.0 for the total energy and kaon scattering angle, respectively, in the γ Ã γ center-of-mass system. These results are based on a data sample of 759 fb −1 collected with the Belle detector at the KEKB asymmetric-energy e þ e − collider. For the first time, the transition form factor of the f 0 2 ð1525Þ meson is measured separately for the helicity-0, -1, and -2 components and also compared with theoretical calculations. We have derived the cross section for the process for W < 2.6 GeV from 121 signal candidate events. Finally, the γ Ã γ partial decay widths of the χ c0 and χ c2 mesons are measured as a function of Q 2 based on 10 candidate events in total.

“…The measurement presented here is based on a data sample containing 772 × 10 6 BB pairs collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e + e − (3.5 GeV on 8.0 GeV) collider [19,20]. At KEKB, BB pairs are produced with a Lorentz boost of βγ = 0.425 nearly along the +z direction, which is opposite the positron beam direction.…”

We present a measurement of the time-dependent CP violation parameters in B 0 → η K 0 decays. The measurement is based on the full data sample containing 772 × 10 6 BB pairs collected at the Υ(4S) resonance using the Belle detector at the KEKB asymmetric-energy e + e − collider. The measured values of the mixing-induced and direct CP violation parameters are: sin 2φ eff 1 = +0.68 ± 0.07 ± 0.03, A η K 0 = +0.03 ± 0.05 ± 0.04, where the first uncertainty is statistical and the second is systematic. The values obtained are the most accurate to date. Furthermore, these results are consistent with our previous measurements and with the world-average value of sin 2φ 1 measured in B 0 → J/ψK 0 decays.
