The variable flavor number scheme to three-loop order
J. Ablinger, A. Behring, J. Blümlein +4
We describe the variable flavor number scheme to three-loop order, which modifies the massless parton densities by single- and two-mass effects and introduces heavy-quark parton di…

The complete three-loop unpolarized and polarized massive operator matrix elements and asymptotic Wilson coefficients
J. Ablinger, A. Behring, J. Blümlein +4
We report on the three-loop unpolarized and polarized massive operator matrix elements, with single- and two-mass corrections, and the associated deep-inelastic massive Wilson coef…

The three-loop single-mass heavy-flavor corrections to the structure functions and
J. Ablinger, A. Behring, J. Blümlein +4
We present quantitative results on the single-mass heavy-flavor contributions in the region of large virtualities up to three-loop order to the unpolarized structure function…
