Event-by-event reconstruction of air-shower events with IceCube using a two component lateral distribution function

The IceCube Neutrino Observatory, located at the geographic South Pole, consists of a surface detector comprised of ice-Cherenkov tanks, IceTop, and an optical in-ice array. This combination allows for coincident measurements of the low-energy (∼ GeV) and high-energy ( 400 GeV) muon component in cosmic-ray air shower events. An event-by-event GeV muon estimator can constitute a useful tool for, amongst others, cosmic ray composition analyses and, in combination with the TeV muon component, strongly constrain hadronic interaction models. However, since IceTop does not feature dedicated muon detectors, an estimation of the GeV muon component on basis of individual air showers is challenging. One possibility for an event-by-event estimation of low-energy muons is given by the two component lateral distribution function (two component LDF), combining an analytical description for the electromagnetic and muon lateral distribution of the full detector signal.
