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…
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…
Dilogarithm ladders from Wilson loops
Marco S. Bianchi, Matias Leoni
We consider a light-like Wilson loop in N=4 SYM evaluated on a regular n-polygon contour. Sending the number of edges to infinity the polygon approximates a circle and the expectat…
On the ABJM four-point amplitude at three loops and BDS exponentiation
Marco S. Bianchi, Matias Leoni
We study the three-loop four-point amplitude in ABJM theory. We determine the dual conformal invariant integrals with highest number of propagators and fix their coefficients by tw…
One Loop Amplitudes In ABJM
Marco S. Bianchi, Matias Leoni, Andrea Mauri +2
For three dimensional N=6 superconformal field theories we compute one-loop scattering amplitudes for any number of external particles. We focus on a particular subsector of N=2 in…
On the infrared behaviour of 3d Chern-Simons theories in N=2 superspace
Matias Leoni, Andrea Mauri
We discuss the problem of infrared divergences in the N=2 superspace approach to classically marginal three-dimensional Chern-Simons-matter theories. Considering the specific case…
