Description
Inclusive-jet photoproduction at HERA has shown to be a favorable ground for verifying perturbative QCD with the obtained jet cross-section. Monte-carlo event generator PYTHIA8 is used to compare the data of ZEUS collaboration aiming for high precision measurements of $\alpha_s$ at HERA. Inclusive-jet photoproduction in the reaction $e^++p \rightarrow e^++jet+X$ with beam energies $E_p$ = 920 GeV, $E_e$ = 27.5 GeV and centre-of-mass energy $\sqrt{s}$ = 318 GeV is analyzed using different parton distribution function (PDFs) and jet reconstruction algorithm such as, $k_T$, anti-$k_T$ and SIScone. A better fit for parton content of photon is required for precision phenomenology at Electron-Ion collider, the successor of HERA that will be colliding spin polarized electrons and ions at energy scales from 29-141 GeV. The framework developed from the validated results is used in making prediction for differential cross-section at EIC with different centre-of-mass energies (44.7, 63.2, and 141.4 GeV) at low and high photon virtualities. This study further aims to explore the multi-parton interaction from hadronic fluctuation of the exchanged photon.
