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 $A ~_{Q g}^{(3)}$ and $Δ A ~_{Q g}^{(3)}$

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 $A ~_{Q g}^{(3)}$ and $Δ A ~_{Q g}^{(3)}$ in $x$ -space…

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…

The three-loop single-mass heavy-flavor corrections to the structure functions $F_{2} (x, Q^{2})$ and $g_{1} (x, Q^{2})$

J. Ablinger, A. Behring, J. Blümlein +4

We present quantitative results on the single-mass heavy-flavor contributions in the region of large virtualities $Q^{2}$ up to three-loop order to the unpolarized structure function…
