Description

My talk will focus on the calculation of the NNLO contributions to
$b\rightarrow c$ decays with full charm mass dependence. For the
semileptonic decay channel $b \rightarrow cl\overline{\nu}$, we obtain
an analytic result which can be compared to previous known results
obtained via expansions in the mass ratio $m_c/m_b$.
I will also give an outlook on the calculation of the hadronic decay
channels $b\rightarrow c\overline{u}d$ and $b\rightarrow c\overline{c}s$, where similar calculation techniques as in the
semileptonic case will be used.
