Abstract
The MINOS Far Detector is a magnetized planar steel-scintillator detector situated underground at depth of 2070 mwe. A small fraction of the cosmic ray muons observed in the MINOS FD contain multiple muons. These events on average are expected to have originated from either higher mass primaries, or higher energy protons than their single muon counterparts. Using the complete MINOS atmospheric data set we will present the first measurement of the multiple muon events charge ratio Rµ = Nµ+/Nµ−. Systematic uncertainties on the charge ratio were minimized by utilizing data collected with both forward and reversed magnetic field running.
