✦ Synopsis
In high energy particle collision secondary particles will be Catalogue number: ACFS created, among which are also unstable hadron resonances. The code DECAY samples the decay of unpolarized baryon and Program obtainable from: CPC Program Library, Queen's Uni-meson resonances in the laboratory frame. DECAY treats some versity of Belfast, N. Ireland (see application form in this issue) of the resonances including all baryon resonances of the spin 3/2 + decuplet and all meson resonances of the spin 1 -nonet. Computer: ESER and IBM System 370; Installation: Karl-A given resonance decays via two or three particle decay steps Marx-Universität Leipzig, DDR and CERN, Geneva, Switzer-until all decay products are stable particles. land method of solution Operating system: MVT 6.1 The decay of baryon and meson resonances is simulated by a two and three body phase space Monte Carlo model. Programming language used: FORTRAN IV Restriction on the complexity of the problem High -speed storage required: 70 Kbytes Only decay modes according to the particle group tables [1] with branching ratio greater than 1% are considered. The Number of bits in a word: 32 program also treats some decays of charmed mesons and baryons. Peripherals used: card reader and line printer Typical running time Number of lines in combined program and test deck: 899 The decay of a typical resonance into three final stable particle needs approximately 0.01 s of central processor time on an Other program necessary for DECAY:

Experimental kineticists are always faced with the problem of reducing kinetic data to extract physically meaningful information. A particularly vexing problem arises when different models reproduce the data but yield different values for the physical parameters. For over forty-five years Monte Carl
