Abstract

In this technical note we present technical details on various aspects of the framework introduced in [1] aimed at extracting effective Higgs couplings in the h → 4ℓ 'golden channel'. Since it is the primary feature of the framework, we focus in particular on the convolution integral which takes us from `truth' level to 'detector' level and the numerical and analytic techniques used to obtain it. We also briefly discuss other aspects of the framework.
