A new observable in extensive air showers
Original language description
We find that the ratio r(mu e) of the muon to the electromagnetic component of an extended air shower at the ground level provides an indirect measure of the depth X-max of the shower maximum. This result, obtained with the air-shower code AIRES, is independent of the hadronic model used in the simulation. We show that the value of r(mu e) in a particular shower discriminates its proton or iron nature with a 98% efficiency. We also show that the eventual production of forward heavy quarks inside the shower may introduce anomalous values of r(mu e) in isolated events.
