Four-loop photon quark form factor and cusp anomalous dimension in the large- limit of QCD
Johannes Henn, Roman N. Lee, Alexander V. Smirnov +2
We compute the four-loop QCD corrections to the massless quark-anti-quark-photon form factor in the large- limit. From the pole part we extract analytic expressions for…
Evaluating the last missing ingredient for the three-loop quark static potential by differential equations
Roman N. Lee, Vladimir A. Smirnov
We analytically evaluate the three-loop Feynman integral which was the last missing ingredient for the analytical evaluation of the three-loop quark static potential. To evaluate t…
Analytic three-loop static potential
Roman N. Lee, Alexander V. Smirnov, Vladimir A. Smirnov +1
We present analytic results for the three-loop static potential of two heavy quarks. The analytic calculation of the missing ingredients is outlined and results for the singlet and…
Total Born cross section of -pair production in relativistic ion collisions from differential equations
Roman N. Lee, Kirill T. Mingulov
We apply the differential equation method to the calculation of the total Born cross section of the process . We obtain explicit expression for the cross se…
