The overall objective of my research is to deepen our understanding of the internal structure of nuclei and nucleons.In the coming years, the Electron-Ion-Collider (EIC) in the United States will enable researchers to study lepton-hadron collisions with unprecedented precision. In particular, it will be the very first collider of leptons and nuclei. Its first objective is to advance our knowledge of the partonic content of the hadrons. In order to plan and optimize various measurements, it is essential to include radiative corrections in our simulations for the lepton-hadron reactions. For the time being, there does not exist any automated simulation tools including even only next-to-leading order (NLO) radiative corrections. A NLO code such as this is however vital in light of the development of the EIC in the coming decade.
MadGraph5_aMC@NLO (MG5) is a framework that aims at providing all the elements necessary for the standard model and beyond standard model phenomenologies, such as the computations of cross sections, the generation of hard events and their matching with event generators, and the use of a variety of tools relevant to event manipulation and analysis. The code allows one to simulate processes in virtually all configurations of interest, in particular for hadronic and e+e- colliders. The aim of my PhD work is to include electron-proton collisions and then extend the work for the electron-nucleus collisions inside MG5. In case of electron-proton collisions there are two regimes: photoproduction & deep-inelastic collisions (DIS). In this study, we are going to present the development of photoproduction at NLO (without parton shower) where the photon is coming from an electron by comparing our results with experimental data from HERA (a particle accelerator) and with theoretical predictions. Moreover, we will also present the development of DIS at leading order (LO) with parton shower mode which describes the particles and the radiation resulting from high-energy particle collisions.
