A parameterisation of single and multiple muons in the deep water or ice

Abstract

A new parameterisation of atmospheric muons deep underwater (or ice) is presented. It takes into account the simultaneous arrival of muons in bundle giving the multiplicity of the events and the muon energy spectrum as a function of their lateral distribution in a shower.
