Parton level study of high ET jets in hard QCD processes at LHC

TL;DR

This paper estimates high transverse energy jet production at the LHC using PYTHIA8 simulations across various energies, analyzing their origins from different parton scattering processes and potential for flavor-specific measurements.

Contribution

It provides detailed predictions for high $E_T$ jet production at the LHC using standard PDFs and PYTHIA8, including flavor-specific cross section estimates.

Findings

High $E_T$ jets dominate at the LHC energies.

Simulations suggest measurable b-flavored jet cross sections up to a few TeV.

Predictions span multiple center-of-mass energies, including future LHC runs.

Abstract

Inclusive jet production will dominate the high $Q^{2}$ final states at the LHC.~In this work we try to estimate the up-to-date expectations, for high $E_{T}$ jets and their expected origin from the various parton-parton scattering processes. For these studies we have used a standard Parton Distribution Function (PDF) and simulated millions of events with the PYTHIA8 event genertor. The results are compared with simulations for center-of-mass energies of 0.9 TeV, 2.36 TeV, 7 TeV and 14 TeV corresponding to existing and future LHC runs. We present some expectations for the relative cross sections of different quark flavours which indicates that eventually we might be able to measure the cross section for b-flavoured jets with reasonable accuracy up to an $E_T$ of a few TeV.
