A Study on Rare Radiative Decay Bc→Dsγ in Technicolor Models

  •  Physics Department of Henan Normal University, Xinsiang 4530022 Institute of Hight Energy Physics, The Chinese Academy of Sciences, Beijing 100080

  • We calulate the psedo-Goldstone-bosons (PGB) contributions to the decay Bc→Ds γ in one generation technicolor model (TCI) and the technicolor model with massless doublet (TCⅡ),and compare with the contributions estimated in the standard model. We find that the contributions of PGBs in the TCI to the electri-magnetic penguin dirgram are large, whereas those of the TCⅡ are small. However, the contributions to the weak annihilation diagrams can be neglected. It is expected that the difference of the branching ratio Br (Bc→Dsγ)in various models can be studied at LHC in near future, and will be an important test to different models.

Abstract: We calulate the psedo-Goldstone-bosons (PGB) contributions to the decay Bc→Ds γ in one generation technicolor model (TCI) and the technicolor model with massless doublet (TCⅡ),and compare with the contributions estimated in the standard model. We find that the contributions of PGBs in the TCI to the electri-magnetic penguin dirgram are large, whereas those of the TCⅡ are small. However, the contributions to the weak annihilation diagrams can be neglected. It is expected that the difference of the branching ratio Br (Bc→Dsγ)in various models can be studied at LHC in near future, and will be an important test to different models.
