PYTHIA 5.7 and JETSET 7.4 are two main components of the 'Lund Monte Carlo' program suite used for generating high-energy-physics events. These events simulate the outcomes of interactions between two incoming particles, aiming to match the average behavior and fluctuations of real data. The programs combine analytical results with various models to describe physics, covering both standard and beyond-standard models. Key components include hard-scattering matrix elements, parton distributions, initial- and final-state radiation, multiple interactions, beam remnants, fragmentation, and decays. A brief outline of programming aspects is also provided. A detailed physics description and manual are available separately.
PYTHIA 5.7 and JETSET 7.4 are designed for IBM 9000, SUN SPARC ELC, and other machines with Fortran 77 compilers. They are compatible with Fortran 90 and require 420 kwords of memory. The programs are not vectorized and use a total of 3 + 18507 + 11261 lines of code. They are available from the CPC Program Library, Queen's University of Belfast, and include separate documentation of about 300 pages. Keywords include QCD, standard model, beyond standard model, hard scattering, e+e- annihilation, leptoproduction, photoproduction, hadronic processes, high-p_t scattering, prompt photons, gauge bosons, Higgs physics, parton distribution functions, jet production, parton showers, fragmentation, hadronization, beam remnants, multiple interactions, particle decays, and event measures.
The programs simulate high-energy collisions between elementary particles, producing complex final states with large multiplicities of hadrons, leptons, neutrinos, and photons. The relationship between these final states and the underlying physics is complex due to incomplete understanding of the physics and the large multiplicities. Events are generated using Monte Carlo methods, simulating aspects like hard-process selection, initial- and final-state radiation, beam remnants, fragmentation, and decays. The programs are used to extract physics from comparisons with existing data or study physics at future experiments.
The new versions of PYTHIA and JETSET supersede previous versions, with significant rewriting and expansion. They handle a wide range of processes, including hard QCD processes, heavy-flavour production, prompt-photon production, photon-induced processes, deep inelastic scattering, W/Z production, standard model Higgs production, gauge boson scattering, and non-standard Higgs production. The programs also include options for studying new gauge bosons, fourth-generation fermions, leptoquarks, technicolour, and compositeness.
PYTHIA contains a rich selection of hard processes, including 2 → 1, 2 → 2, and 2 → 3 processes, while JETSET has only two hard processes.
