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 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…

CP Violation Problem
Nicolai Popov, William J. Briscoe, Igor Strakovsky
The strong CP violation problem has a long history emanating from its discovery 60 years ago in the decay of neutral kaons and subsequent experimental and theoretical studies over…
