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…
The heavy quark-antiquark asymmetry in the variable flavor number scheme
A. Behring, J. Blümlein, A. De Freitas +3
The twist-2 heavy-quark and antiquark distributions, as defined in the variable flavor number scheme, turn out to be different due to QCD corrections from three-loop onward. This i…
The two-mass contributions to the three-loop massive operator matrix elements and
J. Ablinger, J. Blümlein, A. De Freitas +3
We calculate the two-mass three-loop contributions to the unpolarized and polarized massive operator matrix elements and in -spac…
The Single-Mass Variable Flavor Number Scheme at Three-Loop Order
J. Ablinger, A. Behring, J. Blümlein +4
The matching relations in the unpolarized and polarized variable flavor number scheme at three-loop order are presented in the single-mass case. They describe the process of massiv…
