A. Guglielmi, REPORT ON SPY RESULTS - SECONDARY PARTICLE YIELDS FROM 450 GEV C PROTONS ON BERYLLIUM/, Nuclear physics. B, Proceedings supplement, 66, 1998, pp. 387-390
Measurements of pi(+/-) and K+/- production rates from 450 GeV/c proto
ns on beryllium targets were performed in the low momenta range down t
o 7 GeV/c where no data exist. Preliminary results on K+/-/pi(+/-) pro
duction ratios of great importance for neutrino flux calculations at p
resent and future oscillation experiments are presented.
