Production of pions, kaons, and muons by 16-GeV protons

Cross sections for a variety of particles produced from a 16-GeV proton beam collision with target protons are calculated directly for specified momenta and angles. These results are compared with Monte Carlo calculations for particle production cross-sections: the Sanford-Wang cross-section formula and the Sanford-Wang cross-section fomula plus kinematic reflection. Some of these particles decay near the target, forming cloud daughter particles. Monte Carlo distributions of cloud pions from the decay K/sub short/0 → π+π- and cloud muons from π+ → μ+nu are calculated. The trajectories of random rays of cloud particles, which result from a decay within and pass through a specified beam pipe, are traced back to the target plane and plotted. The beam pipe is 1 m long and 20 cm in diameter. There is an elliptical aperture that is 20 cm horizontally and 2 cm vertically. Cloud particles are constrained in angle, less than 100 mrad with respect to the horizontal axis and less than 10 mrad with respect to the vertical axis
