Renormalons as Saddle Points
Arindam Bhattacharya, Jordan Cotler, Aurélien Dersy +1
Instantons and renormalons play important roles at the interface between perturbative and non-perturbative quantum field theory. They are both associated with branch points in the…
Learning the Simplicity of Scattering Amplitudes
Clifford Cheung, Aurélien Dersy, Matthew D. Schwartz
The simplification and reorganization of complex expressions lies at the core of scientific progress, particularly in theoretical high-energy physics. This work explores the applic…
The Collective Coordinate Fix
Arindam Bhattacharya, Jordan Cotler, Aurélien Dersy +1
Collective coordinates are frequently employed in path integrals to manage divergences caused by fluctuations around saddle points that align with classical symmetries. These coord…
