It is based on perturbative QCD plus phenomenological models for parton and beam jet fragmentation.
The manual describes the physics and explains how to use the program.
ISAJET is written in Fortran 77 (with a few common extensions). While ISAJET was previously distributed using the Patchy code management system contained in Cernlib, the Isajet 7.87 version no longer requires Cernlib/Patchy and is distributed as a tarball.
The Isajet tarball can be be unpacked and compiled on any supported Unix system by editing the Makefile and selecting the appropriate options.
Compiling ISAJET on any other computer with ANSI Fortran 77 should be straightforward.
Isajet contains the subprograms Isasugra and Isasusy which are used for generating superparticle mass spectra and decay branching fractions in a variety of supersymmetric models.
Since release 7.72, ISAJET has been interfaced with IsaTools, which contains
We especially thank Alexander Belyaev for his contributions to Isatools.
We express deep thanks to Andrew Box for embedding his RGEFLAV code into Isajet 7.81. The release memo describes changes from the previous version. A history of changes in contained in isajet.car.
