Atomic-weight dependence of muon-pair production in 225-GeV/cπ−-nucleus interactions
Abstract
In an experiment performed at Fermi National Accelerator Laboratory, the production of massive muon pairs in 225-GeV/c ${\ensuremath{\pi}}^{\ensuremath{-}}$-nucleus interactions has been studied for four nuclear targets. Comparison of the relative cross sections enables the dependence on atomic weight $A$ to be determined. If this dependence is parametrized such that the dimuon production cross section ${\ensuremath{\sigma}}_{\ensuremath{\mu}\ensuremath{\mu}}$ is proportional to ${A}^{\ensuremath{\alpha}}$ this experiment yields $\ensuremath{\alpha}=0.98\ifmmode\pm\else\textpm\fi{}0.04$ for $4<{m}_{\ensuremath{\mu}\ensuremath{\mu}}<8.5$ GeV/${\mathit{c}}^{2}$, where ${m}_{\ensuremath{\mu}\ensuremath{\mu}}$ is the invariant mass of the muon pair.
