Renormalon Saddles in the OPE
Arindam Bhattacharya, Jordan Cotler, Aurélien Dersy +1
The cancellation of renormalon ambiguities in the operator product expansion is usually formulated as a matching between perturbative Borel ambiguities and prescription dependence…
EFT Approaches to Sommerfeld Enhancement and Bound States in Singular Potentials
Arindam Bhattacharya, Rashmish K. Mishra, Tracy R. Slatyer
The Sommerfeld enhancement (SE) from long-range interactions, and the related bound state formation rate, can be important non-perturbative inputs to dark matter (DM) annihilation…
Observable Optimization for Precision Theory: Machine Learning Energy Correlators
Arindam Bhattacharya, Katherine Fraser, Matthew D. Schwartz
The practice of collider physics typically involves the marginalization of multi-dimensional collider data to uni-dimensional observables relevant for some physics task. In any cas…
A Precise Determination of from the Heavy Jet Mass Distribution
Miguel A. Benitez, Arindam Bhattacharya, Andre H. Hoang +4
A global fit for is performed on available data for the heavy jet mass distribution. The state-of-the-art theory prediction includes fixed-…
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…
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…
