Abstract
This paper presents the results on
charged particle yields and
production ratios as
measured by the NA56/SPY experiment for 450 GeV/c proton
interactions on beryllium targets. The data cover
a secondary momentum range from
7 GeV/c to 135 GeV/c and pT values up to
600 MeV/c.
An experimental accuracy on the measured yields in the range
from 
to 
, depending on the
beam momentum, and around 
for the particle
production ratios has been achieved.
These measurements are relevant for a precise evaluation
of fluxes and composition
of neutrino beams at accelerators.
Results on the target thickness and shape dependence
are also reported. Inclusive invariant cross sections in the forward direction
have been derived.
