Abstract

The bsγb \rightarrow s \gamma, bdγb \rightarrow d \gamma and bs+b \rightarrow s \ell^+ \ell^- processes are allowed at higher order via the electroweak loop or box diagrams in the Standard model. It is sensitive probe to search for new physics beyond the Standard model because new particles might enter in the loop. We present preliminary results of branching fraction of the BˉXsγ\bar{B} \rightarrow X_s \gamma, CPCP asymmetry in the BˉXs+dγ\bar{B} \rightarrow X_{s+d} \gamma, and the forward-backward asymmetry in the BˉXs+\bar{B} \rightarrow X_s \ell^+ \ell^-. The results are based on a data sample containing 772×106BBˉ772 \times 10^6 B\bar{B} pairs recorded at the Υ(4S)\Upsilon(4S) resonance with the Belle detector at the KEKB e+ee^+ e^- collider.
