Contribution of Muon Pairs to the Yield of Single Prompt Muons

Abstract
Using data from our recent experiment on inclusive μ-pair production by 150-GeV/c protons on beryllium, we have calculated the contribution of muon pairs to the yield of single prompt muons. We find, both at 90° in the center-of-mass system and in the forward direction, that the resulting single-muon cross sections are in reasonable agreement with the existing measurements for which only one muon is detected.
