~1% of the muons are produced by gamma -> mu+ mu- from gammas emitted by muons and therefore have a weight of 1e-4*1e-4 = 1e-8. | ||||||||

The number of muons/antimuons per primary halo particle hitting the sampler at QD0 is (5.56 +/- 0.01) X 10^(-5). Assuming 2 X 10^(10) particles per bunch, and a halo population factor of 10^(-3), there are 1113 +/- 2 muons/antimuons per bunch (here +/- is the statistical uncertainty in the estimate of the mean). | ||||||||
