The logarithmic contributions to the [Formula: see text] asymptotic massive Wilson coefficients and operator matrix elements in deeply inelastic scattering.
We calculate the logarithmic contributions to the massive Wilson coefficients for deep-inelastic scattering in the asymptotic region [Formula: see text] to 3-loop order in the fixed flavor number scheme and present the corresponding expressions for the massive operator matrix elements needed in the variable flavor number scheme. Explicit expressions are given in Mellin [Formula: see text]-space.
