ABJM quantum spectral curve at twist 1: algorithmic perturbative solution

R. N. Lee, A. I. Onishchenko

We present an algorithmic perturbative solution of ABJM quantum spectral curve at twist 1 in sl(2) sector for arbitrary spin values, which can be applied to, in principle, arbitrar…

Differential equations, recurrence relations, and quadratic constraints for $L$ -loop two-point massive tadpoles and propagators

Roman N. Lee, Andrei A. Pomeransky

We consider $L$ -loop two-point tadpole (watermelon) integral with arbitrary masses, regularized both dimensionally and analytically. We derive differential equation system and recu…

Master integrals for two-loop $C$ -odd contribution to $e^{+} e^{-} \to ℓ^{+} ℓ^{-}$ process

Roman N. Lee, Kirill T. Mingulov

We calculate two-loop master integrals for the process of heavy lepton pair production in $e^{+} e^{-}$ collisions. We consider the $C$ -odd diagrams with three photons in the intermedia…

Four-loop quark form factor with quartic fundamental colour factor

Roman N. Lee, Alexander V. Smirnov, Vladimir A. Smirnov +1

We analytically compute the four-loop QCD corrections for the colour structure $(d_{F}^{ab c d})^{2}$ to the massless non-singlet quark form factor. The computation involves non-trivial…
