Evanescent Operators, Scheme Dependences and Double Insertions

Stefan Herrlich, Ulrich Nierste

The anomalous dimension matrix of dimensionally regularized four-quark operators is known to be affected by evanescent operators, which vanish in $D = 4$ dimensions. Their definition…

The determination of $∣ V_{c b} ∣$ from semileptonic inclusive decay rates

U. Nierste

We report on the determination of $∣ V_{c b} ∣$ from the comparison of the semileptonic inclusive decay rates of B-- and D--mesons using the heavy quark symmetry of QCD. While the ren…

The Mass Definition in Hqet and a New Determination of V $_{cb}$

P. Ball, U. Nierste

Positive powers of the mass parameter in a physical quantity calculated with the help of heavy quark effective theory originate from a Wilson coefficient in the matching of QCD and…
