Proposal for the validation of Monte Carlo implementationsof 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 implementationsof 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 standardmodel effective field theory. It is based on the numerical comparison of squared amplitudescomputed at specific phase-space and parameter points in pairs of implementations. Interac-tions are fully linearised in the effective field theory expansion. The squares of linear effectivefield theory amplitudes and their interference with standard-model contributions are comparedseparately. Such pairwise comparisons are primarily performed at tree level and a possibleextension to the one-loop level is also briefly considered. We list the current standard modeleffective field theory implementations and the comparisons performed to date.
