Abstract

Sherpa is a general-purpose Monte Carlo event generator for the simulation of particle collisions in high-energy collider experiments. We summarize essential features and improvements of the Sherpa 2.2 release series, which is heavily used for event generation in the analysis and interpretation of LHC Run 1 and Run 2 data. We highlight a decade of developments towards ever higher precision in the simulation of particle-collision events.

Author comments upon resubmission

We would like the referees for their careful and detailed considerations of our manuscript. Addressing the comments and requests helped us improve the quality of the paper. Accordingly, we have submitted a revised version to the arXiv. The detailed replies and the corresponding changes to the draft or listed below.

We hope that the new version meets the requirements and the paper can be published in its current form.

List of changes

In addressing the referees comments we have extended the presentation of the non perturbative model in Sherpa, in particular Sec. 2.7 and 2.8. Furthermore, we added a section on tuning of the various model parameters and now provide an appendix that lists the default-tune parameters.

We have furthermore clarified the treatment of mass effects in the parton shower. Also, we more clearly state the default assumed for the strong coupling in the simulations.

Lastly, we have fixed a number of minor grammatical mistakes.

Missing the verb in the original comment, it should read 'We would like to thank the referees ...'

Apologies for that.
