Query: Radiative B_c -> tau nu_tau gamma decay   The radiative "B_c -> tau nu_tau gamma" decay is analyzed in the standard
model. The branching ratio of this decay is calculated and the contributions of
the Bremstrahlung and structure dependent parts are compared. It is shown that
this decay can be detected at LHC.
