This paper reports on the charged K/pi production ratios and on the shape of the p(T) distributions of pi fluxes measured by the SPY/NA56 experiment for 450 GeV/c proton interactions on beryllium targets. The present data cover a secondary momentum range from 7 GeV/c to 135 GeV/c in the forward direction and with p(T) values up to 600 MeV/c. An experimental accuracy of about 3% has been achieved. These results will reduce the uncertainty on the estimation of the nu(e) component of neutrino beams. (C) 1998 Published by Elsevier Science B.V.

Abstract
This paper reports on the charged K/pi production ratios and on the shape of the p(T) distributions of pi fluxes measured by the SPY/NA56 experiment for 450 GeV/c proton interactions on beryllium targets. The present data cover a secondary momentum range from 7 GeV/c to 135 GeV/c in the forward direction and with p(T) values up to 600 MeV/c. An experimental accuracy of about 3% has been achieved. These results will reduce the uncertainty on the estimation of the nu(e) component of neutrino beams. (C) 1998 Published by Elsevier Science B.V.
