Abstract

We present measurements of

ψ

production and subsequent dimuon decay from 400-GeV/c proton interactions in an iron target over a range of

P_{t}

from 0 to 4 GeV/c and

x_{F}

from - 0.25 to 0.40. The best fits give

\frac{Ed σ}{d x_{F}} \propto {(1 - | x_{F} |)}^{2.96 \pm 0.27}

and

\frac{d σ}{d {P_{t}}^{2}} \propto \exp (- 2.23 \pm 0.05 P_{t})

for

P_{t} > 1.2

GeV/c. The observed values of

{\frac{Bd σ}{dy} |}_{y = 0}

and

B σ

are 14.0±2.9 and 22.9±4.7 nb/nucleon, respectively.
