A quark-gluon plasma (QGP) is very hot and dense quantem chromodynemics (QCD) matter in which quarks and gluons are deconfined. A QGP can be created by colliding two relativistically accelerated ions, which is of interest because the early universe was in this state shortly after the Big Bang. To create QGP in the lab, Large Hadron Collider (LHC) at Conseil europ´een pour la recherche nucl´eaire (CERN) and Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory (BNL) have collided various kinds of nuclei. One broadly used method to study the properties of a QGP is to compare the cross sections of high-transverse-momentum ($p_{T}$) hadrons in proton-proton (pp) and in heavy-ion collisions. The suppression of high-$p_{T}$ hadrons in heavy-ion collisions, called jet quenching, serves as a signature of a QGP. Recently, however, several other effects, including nucleus PDF and cold nuclear matter effect, which cannot be ignored in accounting for jet quenching, were reported to fully understand those effects, researchers must measure precisely quarkonia, high-$p_{T}$ hadrons, and Z and W bosons in proton-nucleus collisions. For this purpose, the LHC carried out proton-lead collisions at a centre-of-mass energy of 8.16 TeV. In this paper, we introduce the extrapolation method to produce the Z-boson cross section in proton-proton collisions at 8.16 TeV. The ultimate goal is to provide reference data to be compared with the differential cross section for this proton-lead pPb collision.
