Abstract
The present paper incorporates the effects induced by massless spectator quarks in the renormalization group improved Wilson coefficients associated to the 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 with that accuracy.
