Title of program: HADRIN
Nature of the physical problem
The inelastic interaction of a high energy hadron with a nucleon Catalogue number: AADN at rest is sampled via the excitation of hadronic resonance(s) and their subsequent decay. The model uses the most im-Program obtainable from: CPC Program Library, Queen's Uni-portant resonance excitation cross sections and the resonance versity of Belfast, N. Ireland (see application form in this issue) decay model, described in ref. El]. The energy, the momenta and additive quantum numbers are conserved in the model. Computer for which the program is designed and others upon which it is operable: ESER, IBM System 370 Method of solution The Monte Carlo simulation of events is done using tabulated interaction cross sections and empirical formulae. The reso-Computer: ESER 1040; Installation: Karl-Marx-University nance decay is described by the Monte Carlo code DECAY. Leipzig, GDR Typical running time Operation system: MVT, SVS HADRIN simulates one inelastic hadron nucleon interaction in about 10 ms central processor time on an ESER 1040 computer Programming language used: FORTRAN IV and in 0.4 ms on an IBM 3081 computer, dependent on the primary energy and the demanded decay level of particles and High speed storage required: 18000 words resonances. Number of bits in a word: 32 Restriction on the complexity of the problem For all hadron-nucleon reactions the reaction channels are taken into account only, if they contribute more than about 1 Peripheral used: line printer or 2% to the total reaction cross section. The allowed primary hadrons are pions, kaons, nucleons and their antiparticles, Number of lines in combined program and test deck: 2400 secondary particles may be hyperons and antihyperons additionally. The primary hadrons may have laboratory energies Other programs necessary for HADRIN: Monte Carlo code up to about 5 GeV.
