PYTHIA 8

Welcome to PYTHIA - The Lund Monte Carlo!

PYTHIA 8 is still incomplete, in particular with respect to the intended process library, and not yet tuned up for production runs. What is offered here is a snapshot, to allow testing and feedback. The program is under active development, however, and is intended to replace the existing PYTHIA 6 as the official version by the end of 2007.

Use the left-hand index to navigate in the existing documentation. Also note that there is a separate Brief Introduction (as a pdf file), that offers the best way to get to understand the basic structure of PYTHIA 8. The current pages offer the more detailed picture, with the corresponding danger of then losing overview.

The complete PYTHIA 6.4 Physics and Manual, published in
T. Sjöstrand, S. Mrenna and P. Skands, JHEP05 (2006) 026,
in detail describes the physics (partly) implemented also in PYTHIA 8. It therefore is the main reference that you should quote, whether you use PYTHIA 6 or PYTHIA 8.
