ISAJET 7.69: A Monte Carlo Event Generator for pp, $\bar pp$, and $e^=e^-$ Reactions
Howard Baer, Frank E. Paige, Serban D. Protopescu, Xerxes Tata
TL;DR
ISAJET 7.69 delivers a comprehensive Monte Carlo event generator for pp, p pbar, and e+e- collisions, integrating complete 1-loop SUSY mass corrections, expanded SUSY frameworks (MSSM, SUGRA, GMSB, AMSB), and improved RGEs with Higgs vevs. It combines perturbative hard scattering, leading-log QCD radiation, and independent jet fragmentation with beam-jet modeling, plus a suite of higher-order and multiparton capabilities via MadGraph/HELAS, enabling Z+2 jet processes and beyond. The release emphasizes improved electroweak symmetry breaking convergence, refined gauge couplings, and broader process coverage (including e+e- options, extra dimensions, and technicolor) to enhance predictive power for collider phenomenology. Practically, ISAJET remains a versatile tool for simulating complex final states in hadron and lepton colliders, with extensible SUSY modeling and patchable, cross-platform code management through Patchy/PAM.
