The canonical form has got baubles
Marco S. Bianchi, Matias Leoni
The method of differential equations in canonical form has proven a powerful tool for solving multiloop Feynman integrals. In this note we test this procedure away from four dimens…
A planar doublebox in canonical form
Marco S. Bianchi, Matias Leoni
We consider a planar doublebox with four massive external momenta and two massive internal propagators. We derive the system of differential equations for the relevant master integ…
The quantum 1/2 BPS Wilson loop in Chern-Simons-matter theories
Marco S. Bianchi, Luca Griguolo, Matias Leoni +3
In three dimensional Chern-Simons-matter theories two independent fermionic Wilson loop operators can be defined, which preserve half of the supersymmetry charges and…
An exact limit of ABJM
Marco S. Bianchi, Matias Leoni
We study planar ABJM in a limit where one coupling is negligible compared to the other. We provide a recipe for exactly solving the expectation value of bosonic BPS Wilson loops on…
Green-Schwarz superstring on the lattice
Lorenzo Bianchi, Marco S. Bianchi, Valentina Forini +2
We consider possible discretizations for a gauge-fixed Green-Schwarz action of Type IIB superstring. We use them for measuring the action, from which we extract the cusp anomalous…
A note on multiply wound BPS Wilson loops in ABJM
Marco S. Bianchi
We consider BPS Wilson loops in planar ABJM theory, wound multiple times around the great circle. We compute the expectation value of the 1/6-BPS and 1/2-BPS Wilson loops to three-…
