gg→HH NLO EW corrections in the forward limit — •Dominik Grau1, Daniel Stremmer1, Matthias Steinhauser1, Joshua Davies2, and Kay Schönwald3 — 1Karlsruher Institut für Technologie, Karlsruhe, Deutschland — 2University of Liverpool, Liverpool, United Kingdom — 3Cern, Genève, Switzerland
In this talk, we present the calculation of the NLO EW corrections to di-Higgs production via gluon fusion. We compute the electroweak amplitude using analytical approximations around the forward limit, which cover large parts of the phase space with sufficient accuracy. Our results are given in symbolic form, offering flexibility with respect to parameter value and renormalization scheme choices.
