- | 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) | + | A question that often arises is whether dimension-8 effects compromise present analysis testing dimension-6 ones.

- | Here we want to compute a class of dimesnion-8 effects that arises after a change of basis, in such a way that their coefficient is uniquely related to the coefficients of dimension-6 operators. | + | Here we want to compute a class of dimension-8 effects that arises after a change of basis, in such a way that their coefficient is uniquely related to the coefficients of dimension-6 operators. |
The goal of this analysis will be to understand under what conditions we can trust the dimension-6 analysis in the rotated basis. | The goal of this analysis will be to understand under what conditions we can trust the dimension-6 analysis in the rotated basis. | ||
