QCD corrections for subleading powers in $1/m_b$ for the nonleptonic $b\to c\bar{c}s$ transition

Thomas Mannel, Daniel Moreno, Alexei A. Pivovarov

We compute next-to-leading order QCD corrections to the $1/m_b^2$ terms of the Heavy Quark Expansion for the contribution to inclusive nonleptonic bottom hadron decays induced by t…
