# Cross Section Predictions of W ($W\to\ell^{\pm}\nu$) and Z ($Z\to\ell^{+}\ell^{-}$) Bosons in Association with Jets in pp Collisions

## TL;DR

This paper predicts W and Z boson production with jets in proton-proton collisions at 14 TeV using Monte Carlo generators, compares these predictions with existing LHC data, and assesses their accuracy across different energies.

## Contribution

It provides detailed cross section predictions for W and Z bosons with jets at 14 TeV and compares them with NNLO calculations and LHC measurements, enhancing validation of theoretical models.

## Key findings

- NNLO QCD calculations agree well with 8 TeV CMS data.
- Predictions are consistent with 7 TeV and 13 TeV ATLAS results.
- The study improves understanding of boson+jets processes at high energies.

## Abstract

Cross section predictions of W and Z bosons in association with jets (up to 6 jets, $W\to\ell^{\pm}\nu$ and $Z\to\ell^{\pm}$ where $\ell^{\pm}$=$e^{\pm}$ or $\mu^{\pm}$) in proton-proton collisions at $\sqrt{s}$=14 TeV is performed using Alpgen MC generator with CTEQ6L1 leading order parton distribution function. In addition, W and Z boson cross sections are obtained up to next to next to leading order (NNLO) QCD corrections using MCFM MC generator. To validate the predictions, a detailed comparison of NNLO QCD calculations with 8 TeV CMS results for total cross section is performed and a fiducial region is further defined to make a comparison of predictions with 7 TeV and 13 TeV ATLAS results.
