A search for b(c) quark pdf uncertainties at TeV scale ep collider

TL;DR

This paper investigates the uncertainties in parton distribution functions (PDFs) for b(c) quark production at a future TeV-scale electron-proton collider, highlighting significant variations in predicted cross sections.

Contribution

It demonstrates the potential of the LHeC to probe extremely small x(g) regions and quantifies the PDF uncertainties in heavy flavor production processes.

Findings

Maximum cross section difference of 60% between PDFs.

LHeC can reach x(g) > 10^{-6}.

Heavy flavor production is sensitive to PDF uncertainties.

Abstract

We discuss c\bar{c} and b\bar{b} pair productions at ep collider for studying extremely small x(g) region. It has been shown that Large Hadron electron Collider (LHeC) has a reach of about x(g)>10^{-6}. The aim of this work is to show that the PDF uncertainties in the heavy flavour production. Maximum difference of cross section between PDFs 60% has been found in the process of ep\rightarrow eq\bar{q}X.
