abstract
We extend earlier schemes for merging tree-level matrix elements with parton showers to include also merging with one-loop matrix elements. In this paper we make a first study on how to include one-loop corrections, not only for events with a given jet multiplicity, but simultaneously for several different jet multiplicities. Results are presented for the simplest non-trivial case of hadronic events at LEP as a proof-of-concept.

Systematic comparison of three event generators shows they describe photoproduction data adequately, with PYTHIA and SHERPA performing best, and identifies photon PDF refits plus RIVET measurements as prerequisites for EIC precision.
The paper provides a detailed physics and user manual for the PYTHIA 8.3 Monte Carlo event generator used in high-energy physics.
