Measurement of Dimuon Production ats12=62GeV

Abstract

Prompt dimuon production has been measured. Events with mass up to 25 ${\mathrm{G}\mathrm{e}\mathrm{V}/\mathit{c}}^2$ are observed, as well as the $J$ and $\Upsilon$ resonances. Cross sections are given for $J$ and $\Upsilon$ production. For the continuum, the scaling function $F\left(\tau \right)$ is measured at very small values of $\sqrt{\tau }=\frac{m}{\sqrt{s}}$ covering the range $0.05<\mathrm{}\sqrt{\tau }<0.20\mathrm{}$.
