A two-loop application of the threshold expansion: the bottom quark mass from bb production
M. Beneke, A. Signer, V. A. Smirnov
Abstract
We use the threshold expansion and non-relativistic effective theory to determine the bottom quark mass from moments of the bb production cross section at next-to-next-to-leading order in the (resummed) perturbative expansion, and including a summation of logarithms. For the MS mass mb, we find mb(mb)=(4.26 0.12) GeV.
