Observation of B+ -> chi_c0 K+

Belle Collaboration, K. Abe

Using a sample of $31.3 x 1 0^{6}$ B\bar{B}$ pairs collected with the Belle detector at the Y(4S) resonance, we make the first observation of the charged B meson decay to chi_c0 and a…

Observation of Large CP Violation in the Neutral B Meson System

K. Abe, The Belle Collaboration

We present a measurement of the Standard Model CP violation parameter sin 2phi_1 based on a 29.1 fb^{-1} data sample collected at the Upsilon(4S) resonance with the Belle detector…

Observation of $B^{+} \to χ_{c 0} K^{+}$

K. Abe, The Belle Collaboration

We report the first observation of the decay $B^{+} \to χ_{c 0} K^{+}$ using 21.3 fb $^{- 1}$ of data collected by the Belle detector at the $Υ$ (4S) resonance. The preliminary result for…

Observation of B->J/psi K1(1270)

K. Abe, Belle Collaboration

We report the first observation of the exclusive decay process B->J/psi K1(1270) using a sample of 11.2M BBbar meson pairs collected in the Belle detector at the KEKB asymmetric e+…
