Proposal for the validation of Monte Carlo implementations of the standard model effective field theory


Durieux, Gauthier; Brivio, Ilaria; Maltoni, Fabio; Trott, Michael; et al; Isidori, G; Zhang, Hantian (2019). Proposal for the validation of Monte Carlo implementations of the standard model effective field theory. arXiv.org 1906.12310, University of Zurich.

Abstract

We propose a procedure to cross-validate Monte Carlo implementations of the standard model effective field theory. It is based on the numerical comparison of squared amplitudes computed at specific phase-space and parameter points in pairs of implementations. Interactions are fully linearised in the effective field theory expansion. The squares of linear effective field theory amplitudes and their interference with standard-model contributions are compared separately. Such pairwise comparisons are primarily performed at tree level and a possible extension to the one-loop level is also briefly considered. We list the current standard model effective field theory implementations and the comparisons performed to date.
