sin2phi1 with 45 Million BBbar Pairs at Belle

Masashi Hazumi

We present an improved measurement of the standard model CP violation parameter sin2phi1 (also known as sin2beta) based on a sample of 45 x 10^6 BBbar pairs collected at the Upsilo…

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…
