A question that often arises is wheter dimension-8 effects compromise present analysis testing dimension-6 ones. Normally this requires a discussion about the expected size of dimension-8 operators under given assumptions (see for instance “On the Validity of the Effective Field Theory Approach to SM Precision Tests” https://arxiv.org/pdf/1604.06444.pdf)

This page is intended to collect information on EFT uncertainty discussions.

The project aims to compute a set of observables (cross-sections and differential cross-sections) for a given dimension 6 operator and then compare the predictions obtained in different bases. The plan is to use ROSETTA in order to have the same operator (up to dimension 8 contribution).

The differences between different predictions should be at the level of dimension 8 term and should provide an idea of the theoretical uncertainties. We can then compare differences with those related to including or not the new physics square terms.

Kick-off meeting in the QCD room: Monday at 17h30
