Important Note: From 2013 onwards, the recommended and actively developed version is PYTHIA 8, see the Important PYTHIA 6 announcement sent out in December 2012.

PYTHIA 6.4 is the last PYTHIA 6 version, containing the most up-to-date features and bug fixes. It is no longer actively developed but is maintained here in a legacy state. PYTHIA 6.4 was a direct continuation of version 6.3, and version 6.400 contained no news relative to PYTHIA 6.327.

The most recent program plus documentation package consists of:

  • The current version of the PYTHIA code: pythia-6.4.28.f.gz
  • Current update notes, describing the new features in PYTHIA 6.4, especially developments since the publication of the manual
  • Alternatively, you can use svn to check out the latest version: svn co local_directory_name
  • The complete PYTHIA 6.400 manual, published in JHEP 05 (2006) 026
    (LU TP 06-13, FERMILAB-PUB-06-052-CD-T, hep-ph/0603175)
    (including minor updates requested by the referee for the JHEP publication, and the new colour reconnection options in PYTHIA 6.402, as included in version 2 of hep-ph/0603175)
    pdf (with nice cross-referencing), or
    postscript, or
    two-pages-in-one postscript for more economical printing, or
    LaTeX source
