A Critical Reassessment of Q7 and Q8 Matrix Elements

High Energy Physics - Phenomenology 2016-08-16 v2 High Energy Physics - Lattice

Abstract

We compare recent theoretical determinations of weak matrix elements of the electroweak penguin operators Q7 and Q8. We pay special attention to the renormalization scheme dependence of these determinations as well as to the influence of higher dimension operators in the different approaches.
