A Measurement of Lifetime Difference in $D^{0}$ Meson Decays

Belle Collaboration, K. Abe

We report a measurement of the $D^{0}$ - $D ˉ^{0}$ mixing parameter $y_{C P}$ using 23.4 fb $^{- 1}$ of data collected near the $Υ$ (4S) resonance with the Belle detector at KEKB. $y_{…

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->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+…
