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.
My work aims at implementing lepton-hadron collisions in MG5 which are not implemented yet in this framework. It can currently work for the proton-proton and electron-positron collisions but when it comes to the context of lepton-hadron collisions it would not work. The reason resides in the phase-space integration. In the case of electron-proton, it should be handled differently rather than the proton-proton case in MG5.
Until now, I have worked on specific photon-proton collisions where the photon is coming from an electron. This work does not require any change in the phase-space-integration part, though it required some other changes which I have done to work it properly within the MG5 framework.
After this development, my next work is to concentrate on the lepton-hadron collisions part in MG5.
