KKMCee: Multi-photon MC for lepton and quark pair production at lepton colliders

TL;DR

KKMCee is a highly advanced Monte Carlo event generator for lepton and quark pair production in electron-positron collisions, now rewritten in C++ with improved algorithms and verified benchmarks.

Contribution

The paper introduces KKMCee 5.00, a C++ rewrite of a leading Monte Carlo generator with enhanced algorithms and interface improvements.

Findings

KKMCee 5.00 reproduces previous FORTRAN benchmarks.

The new version includes algorithm and interface improvements.

It remains the most sophisticated generator for these processes.

Abstract

We present an overview of the Monte Carlo event generator KKMCee for lepton and quark pair production in the high energy electron-positron annihilation process. We note that it is still the most sophisticated event generator for such processes. Its entire source code has been rewritten in C++. We have verified that the new version, KKMCee 5.00, reproduces the benchmarks of the older code in FORTRAN 77. We discuss a number of improvements in the MC algorithm and its interfaces.
