Accurate simulation of W, Z, and Higgs boson decays in Sherpa
journal contribution
posted on 2023-06-10, 05:12 authored by Frank Krauss, Jonas LindertJonas Lindert, Robin Linten, Marek SchönherrWe discuss the inclusion of next-to–next-to leading order electromagnetic and of next-to leading order electroweak corrections to the leptonic decays of weak gauge and Higgs bosons in the Sherpa event generator. To this end, we modify the Yennie– Frautschi–Suura scheme for the resummation of soft photon corrections and its systematic improvement with fixed-order calculations, to also include the effect of virtual corrections due to the exchange of weak gauge bosons. We detail relevant technical aspects of our implementation and present numerical results for observables relevant for high-precision Drell–Yan and Higgs boson production and decay simulations at the LHC.
