measure the forward–backward asymmetry of the decay of the cosmic-ray muons, offering a
pedagogical view to the parity violation in weak interactions. The detector system consists of
six plastic scintillators installed vertically in row. The backward–forward asymmetry of the
decay e− and e+ with respect to the muon motion direction is correlated with the incident
depth of the muon stopped in the scintillator. MC simulations have been carried out in order …
