A Large Twist Limit for Any Operator
Gwenaël Ferrando, Amit Sever, Adar Sharon +1
We argue that for any single-trace operator in SYM theory there is a large twist double-scaling limit in which the Feynman graphs have an iterative structure. Such str…
Line operators in Chern-Simons-Matter theories and Bosonization in Three Dimensions II -Perturbative Analysis and All-loop Resummation
Barak Gabai, Amit Sever, De-liang Zhong
We study mesonic line operators in Chern-Simons theories with bosonic or fermionic matter in the fundamental representation. In this paper, we elaborate on the classification and p…
Line Operators in Chern-Simons-Matter Theories and Bosonization in Three Dimensions
Barak Gabai, Amit Sever, De-liang Zhong
We study Chern-Simons theories at large with either bosonic or fermionic matter in the fundamental representation. The most fundamental operators in these theories are mesonic…
An Operator Product Expansion for Form Factors III. Finite Coupling and Multi-Particle Contributions
Amit Sever, Alexander G. Tumanov, Matthias Wilhelm
Form factors in planar super-Yang-Mills theory have a dual description in terms of periodic Wilson loops. This duality maps the multi-collinear expansion of the for…
Probing multi-particle unitarity with the Landau equations
Miguel Correia, Amit Sever, Alexander Zhiboedov
We consider the scattering amplitude of identical massive particles. We identify the Landau curves in the multi-particle region . We systematicall…
Rigorous bounds on the Analytic -matrix
Andrea Guerrieri, Amit Sever
We consider a dual -matrix Bootstrap approach in space-time dimensions which relies solely on the rigorously proven analyticity, crossing, and unitarity properties of…
