Form factor recursion relations at loop level
Lorenzo Bianchi, Andreas Brandhuber, Rodolfo Panerai +1
We introduce a prescription to define form factor integrands at loop level in planar supersymmetric Yang-Mills theory. This relies on a periodic kinematic configura…
Dual conformal invariance for form factors
Lorenzo Bianchi, Andreas Brandhuber, Rodolfo Panerai +1
Form factors of the stress-tensor multiplet operator in supersymmetric Yang-Mills reveal surprisingly simple structures similar to those appearing in scattering amp…
Line defects and radiation in theories
Lorenzo Bianchi, Madalena Lemos, Marco Meineri
We study the conformal data of a generic superconformal half-BPS line defect in a four-dimensional theory. We prove a theory independent relation between the one-…
Exact Bremsstrahlung functions in ABJM theory
Lorenzo Bianchi, Michelangelo Preti, Edoardo Vescovi
In this paper we study the Bremsstrahlung functions for the 1/6 BPS and the 1/2 BPS Wilson lines in ABJM theory. First we use a superconformal defect approach to prove a conjecture…
