An Improved Measurement of Mixing-induced CP Violation in the Neutral B Meson System

arXiv (Cornell University) (2002)

Kazuo Abe Y. Chao S. Kobayashi S. Yanaka D. Liventsev

We present an improved measurement of the standard model CP violation parameter sin2phi_1 (also known as sin2beta) based on a sample of 85 times 10^6 B Bbar pairs collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. One neutral B meson is reconstructed in a J/psi K_S, psi(2S) K_S, chi_{c1} K_S, eta_c K_S, J/psi K^{*0}, or J/psi K_L CP-eigenstate decay channel and the flavor of accompanying B meson is identified from itsdecay products. From the asymmetry in the distribution of the time intervals between the two B meson decay points, we obtain sin2phi_1 = 0.719 +/- 0.074(stat) +/- 0.035(syst). We also report measurements of CP violation parameters for the related B^0 -> J/psi pi^0 decay mode and the penguin-dominated processes B^0 -> eta' K_S, phi K_S and K^+K^- K_S.

Measurement ofBd0−B¯d0

Physical Review Letters (2001)

K. Abe K. Abe I. Adachi Byoung Sup Ahn H. Aihara

We report a determination of the B(0)(d)-&B_(0)(d) mixing parameter Deltam(d) based on the time evolution of dilepton yields in Upsilon(4S) decays. The measurement is based on a 5.9 fb(-1) data sample collected by the Belle detector at KEKB. The proper-time difference distributions for same-sign and opposite-sign dilepton events are simultaneously fitted to an expression containing Deltam(d) as a free parameter. Using both muons and electrons, we obtain Deltam(d) = 0.463+/-0.008 (stat)+/-0.016 (syst) ps(-1). This is the first determination of Deltam(d) from time evolution measurements at the Upsilon(4S). We also place limits on possible CPT violations.

Evidence for the Electroweak Penguin Decay $B \to X_{s}\ell^{+}\ell^{-}$}

arXiv (Cornell University) (2001)

Kazuo Abe Y. Chao S. Kobayashi S. Yanaka Katsuhide Misono

We report a search for the flavor-changing neutral current decay $B \to X_{s} \ell^{+} \ell^{-}$ using a 29.5 fb$^{-1}$ data sample accumulated at the $Υ(4S)$ resonance with the Belle detector at the KEKB $e^{+}e^{-}$ storage ring. We observe evidence for $B\to Kμ^+μ^-$ and report the preliminary branching fraction of ${\cal B}(B \to K μ^{+} μ^{-}) = (0.99^{+0.39}_{-0.32}^{+0.13}_{-0.15}) \times 10^{-6}$. We also set the following 90% confidence level upper limits on the branching fractions for exclusive and inclusive decays, ${\cal B}(B \to K e^{+} e^{-}) < 1.2 \times 10^{-6}$, ${\cal B}(B \to K^*(892) e^{+} e^{-}) < 5.1 \times 10^{-6}$, ${\cal B}(B \to K^*(892) μ^{+} μ^{-}) < 3.0 \times 10^{-6}$, ${\cal B}(B \to X_{s} e^{+} e^{-}) < 10.1 \times 10^{-6}$, ${\cal B}(B \to X_{s} μ^{+} μ^{-}) < 19.1 \times 10^{-6}$.

The Physics of the B Factories

The European Physical Journal C (2014)

A. J. Bevan B. Golob Th. Mannel S. Prell B. Yabsley

This work is on the Physics of the B Factories. Part A of this book contains a brief description of the SLAC and KEK B Factories as well as their detectors, BaBar and Belle, and data taking related issues. Part B discusses tools and methods used by the experiments in order to obtain results. The results themselves can be found in Part C. Please note that version 3 on the archive is the auxiliary version of the Physics of the B Factories book. This uses the notation alpha, beta, gamma for the angles of the Unitarity Triangle. The nominal version uses the notation phi_1, phi_2 and phi_3. Please cite this work as Eur. Phys. J. C74 (2014) 3026.

K. Abe K. Abe I. Adachi Byoung Sup Ahn H. Aihara

Using the Belle detector operating at the KEKB e+e− storage ring, we have measured the mean multiplicity and momentum spectrum of neutral pions from the decays of the Υ(4S) resonance. We measure a mean of 4.70±0.04±0.22 neutral pions per Υ(4S) decay.Received 25 March 2001DOI:https://doi.org/10.1103/PhysRevD.64.072001©2001 American Physical Society
