Sensitivity of EAS measurements to the energy spectrum of muons

Popis výsledku v původním jazyce

We have studied how the energy spectrum of muons at production affects some of the most common measurements related to muons in extensive air shower studies, namely, the number of muons at the ground, the slope of the lateral distribution of muons, the apparent muon production depth, and the arrival time delay of muons at ground. We found that by changing the energy spectrum by an amount consistent with the difference between current models (namely EPOS-LHC and QGSJET-II.04), the muon surface density at ground increases 5% at 20 degrees zenith angle and 17% at 60 degrees zenith angle. This effect introduces a zenith angle dependence on the reconstructed number of muons which might be experimentally observed. The maximum of the muon production depth distribution at 40 degrees increases similar to 10 g/cm(2) and similar to 0g/cm(2) at 60 degrees, which, from pure geometrical considerations, increases the arrival time delay of muons.n
