Contribution

It introduces a versatile Monte Carlo tool that includes all relevant electroweak and QCD contributions for six parton final states, with interference effects and compatibility with standard event analysis protocols.

Findings

Generates unweighted events for complex six-parton processes.

Includes interference between electroweak and QCD diagrams.

Applicable to Higgs, boson scattering, and top quark studies.

Abstract

PHANTOM is a tree level Monte Carlo for six parton final states at proton--proton, proton--antiproton and electron--positron collider at O(alpha_ew^6) and O(alpha_ew^4*alpha_s^2) including possible interferences between the two sets of diagrams. This comprehends all purely electroweak contribution as well as all contributions with one virtual or two external gluons. It can generate unweighted events for any set of processes and it is interfaced to parton shower and hadronization packages via the last Les Houches Accord protocol. It can be used to analyze the physics of boson boson scattering, Higgs boson production in boson boson fusion, t-tbar and three boson production.
