Study on the Decay b→sγ in theMultiscale Walking Tchnicolor Model

  • We invesdgate the correction to the branching ratio of decay b→sγ from the Pseudo-Goldstone bosons (PGBs) in the multiscale walking technicolor model (MWTCM). Tbe correction is found so large that we can not explain the recentCLEO data lf topcolor is further introduced. the branching ratio in the topcolor assisted MWTCM will be in agreement with the CLEO data for a certain range of the model-allowed parameter space.

Abstract: We invesdgate the correction to the branching ratio of decay b→sγ from the Pseudo-Goldstone bosons (PGBs) in the multiscale walking technicolor model (MWTCM). Tbe correction is found so large that we can not explain the recentCLEO data lf topcolor is further introduced. the branching ratio in the topcolor assisted MWTCM will be in agreement with the CLEO data for a certain range of the model-allowed parameter space.
