Next-to-leading order radiative corrections to the decay b --> ccs
We calculate the complete {\cal O}(\alpha_s) corrections to the quark decay b\to ccs taking full account of the quark masses, but neglecting penguin contributions. For a c to the b quark mass ratio m_c/m_b= 0.3 and a strange quark mass of 0.2\,GeV, we find that the next-to-leading order (NLO) correc...
