Simulation of the Charge Ratio of Cosmic Ray Muons in Extensive Air Showers using CORSIKA — •Livingstone Ochilo1,2, Nadir Hashim2, and John Okumu2 — 1University of Siegen, Siegen, Germany — 2Kenyatta University, Nairobi, Kenya
The interaction of primary cosmic rays in the atmosphere produces, among other particles, pions and kaons. They decay to muons, which form an important component of extensive air showers. The ratio of positively to negatively charged muons, called the muon charge ratio, provides important information about the cosmic ray interactions in the atmosphere. In this study, the theoretical hadronic interaction models in the cosmic ray simulation code CORSIKA have been used to study the charge ratio of cosmic ray muons simulated in extensive air showers. An East - West effect on the charge ratio of simulated cosmic ray muons is observed. It is more pronounced for inclined and low-energy muons (momentum less than 100 GeV/c and zenith angle greater than 80°). Experimental data from "MINOS Near" experiment gives similar results.
