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.
