Study on decays

Abstract

In anticipation of abundant upsilon data sample at high-luminosity heavy-flavor experiments in the future, we studied nonleptonic two-body weak decays of below the open-bottom threshold with n = 1, 2 and 3. It is found that branching ratios for decays are relatively large among upsilon decay into final states ( , K and K*) and can reach up to 10−10, which is promisingly detected by experiments at the running Large Hadron Collider and forthcoming SuperKEKB.
