| contents | We investigate the substructure of jets produced in photoproduction events with center-of-mass energies $\sqrt{s} = 30\text{--}140$ GeV at the proposed Electron-Ion Collider (EIC). Events are generated using PYTHIA and contributions from direct and resolved photoproduction subprocesses are analyzed at different center-of-mass energies. Jets are reconstructed using longitudinally invariant $k_T$ algorithm within the FastJet framework. Substructure of quark- and gluon-initiated jets in the selected di-jet photoproduction sample is studied in detail by using jet-shape variables. Predictions for subjet multiplicities and integrated jet shapes are presented in the gluon-initiated and quark-initiated jets. These results demonstrate the feasibility of distinguishing quark and gluon jets in the photo-production events at the EIC and provide a baseline for further QCD studies. |
