Inclusive semileptonic b → c ℓ ν ¯ $$ b\to c\ell \overline{\nu} $$ decays to order 1 / m b 5 $$ 1/{m}_b^5 $$
Abstract Inclusive semileptonic B → X c ℓ ν ¯ $$ B\to {X}_c\ell \overline{\nu} $$ decays can be described in the Heavy Quark Expansion (HQE) and allow for a precision determination of the CKM element |V cb |. We calculate the terms of 1 / m b 5 $$ 1/{m}_b^5 $$ and derive a “trace formula” which allo...
