PROPHECY4F 3.0: A Monte Carlo program for Higgs-boson decays into four-fermion final states in and beyond the Standard Model

TL;DR

PROPHECY4F 3.0 is a Monte Carlo program that accurately simulates Higgs boson decays into four-fermion final states across various Standard Model extensions, including higher-order corrections and interference effects.

Contribution

It introduces an advanced Monte Carlo generator capable of detailed Higgs decay simulations with full NLO corrections and interference effects in multiple theoretical frameworks.

Findings

Provides fully differential predictions with NLO corrections

Includes interference contributions between WW and ZZ channels

Generates unweighted events for leptonic final states

Abstract

The Monte Carlo generator PPROPHECY4F provides a PROPer description of the Higgs dECaY into 4 Fermions within the Standard Model, the Standard Model with a fourth fermion generation, a simple Higgs-singlet extension of the Standard Model, and the Two-Higgs-Doublet Model. The fully differential predictions include the full QCD and electroweak next-to-leading-order corrections, all interference contributions between different WW/ZZ channels, and all off-shell effects of intermediate W/Z bosons. PPROPHECY4F computes the inclusive partial decay widths and allows for the computation of binned differential distributions of the decay products. For leptonic final states also unweighted events are provided.
