Measurement of the Branching Fractions for B0s->J/? ? and B0s->J/? K0S Using the Data Taken at e+e?->?(5S) Resonance Energy

by SAYEED, KAZI ABU

We measure the branching fractions for B0s->J/? ? and B0s->J/? K0S decays using 23.6 fb?1 of data collected on the ?(5S) resonance by the Belle detector at the KEKB asymmetric energy e+e? collider. The J/? candidates are reconstructed from both e+e? and ?+?? pairs; ? candidates are reconstructed from K+K? pairs; and K0S candidates are reconstructed from ?+?? pairs.
