One-loop pentagon integral in dimensions from differential equations in -form
Mikhail G. Kozlov, Roman N. Lee
We apply the differential equation technique to the calculation of the one-loop massless diagram with five onshell legs. Using the reduction to -form, we manage to obtain a simp…

Small-angle scattering and quasiclassical approximation beyond leading order
P. A. Krachkov, R. N. Lee, A. I. Milstein
In the present paper we examine the accuracy of the quasiclassical approach on the example of small-angle electron elastic scattering. Using the quasiclassical approach, we derive…
