Drell-Yan, ZZ, W+W- production in SM & ADD model to NLO+PS accuracy at the LHC

TL;DR

This paper computes next-to-leading order QCD corrections for di-lepton and electroweak boson production in the Standard Model and ADD model, matched with parton shower simulations, highlighting deviations at 8 TeV LHC.

Contribution

It provides the first NLO+PS accurate predictions for di-boson production in the ADD model at the LHC.

Findings

Deviations from the Standard Model observed at 8 TeV LHC.

Enhanced accuracy of predictions with NLO+PS matching.

Potential signatures of large extra dimensions in di-boson channels.

Abstract

In this paper, we present the next-to-leading order QCD corrections for di-lepton, di-electroweak boson (ZZ, W+W-) production in both the SM and the ADD model, matched to the HERWIG parton-shower using the aMC@NLO framework. A selection of results at the 8 TeV LHC, which exhibits deviation from the SM as a result of the large extra-dimension scenario are presented.
