Spectator effects in the HQET renormalization group improved Lagrangian at O(1/m3) with leading logarithmic accuracy: Spin-dependent case
Abstract
The present paper incorporates the effects induced by massless spectator quarks in the renormalization group improved Wilson coefficients associated to the O(1/m3) spin-dependent heavy quark effective theory Lagrangian operators. The computation is carried out in Coulomb gauge with leading logarithmic precision. The result completes the Lagrangian to O(1/m3) with that accuracy.
