The main goal of the project is to develop and publish up-to-date Monte Carlo event generation software for full simulations of high-energy electron-ion colliders. Such programs are crucial for performing experimental analysis and designing new detectors as they are able to reproduce full description of individual collision events. Recently most of the event generator development have focused on proton-proton collisions performed at the Large Hadron Collider (LHC) at CERN. Thus, the capabilities of the modern event generators are limited to specific processes or kinematical regions in electron-proton collisions and only some consideration has been given for electron-nucleus interactions. However, full event generators for such colliders are currently in urgent demand due to the future collider porjects that are currently being developed. The most advanced projects are the US-based Electron-Ion Collider (EIC) and Large Hadron electron Collider (LHeC) at CERN.

The proposed research project will mainly consist of extensions and improvements for Pythia 8 general purpose Monte Carlo generator which is the most widely used general-purpose event generator within the LHC experiments. Recently there have been several developments for photoproduction in electron-proton collisions and heavy-ion collisions within Pythia 8 which provide a perfect premise to build upon. Another important goal of the project is to extend automated next-to-leading order corrections also for the electron-positron collisions at all virtualities. This will be achieved within the Powheg framework providing a convenient way to combine higher order matrix element calculations with parton showers. In addition to future electron-ion colliders, such a framework could be applied also to ultra-peripheral collisions which have recently gathered an increasing amount of interested within the LHC experiments. In these events it is possible to study photon-proton and photon-nucleus interactions with quasi-real photons. Such collisions can provide an additional handle to study the unexpected collective effects observed in small collision systems. A thorough understanding on these effects is important for the particle physics community and a Monte Carlo event generator for such processes including recent developments on hadronization models would offer a valuable and flexible platform to study such effects further.
