EeV Hadronic Showers in Ice: The LPM effect

We study the longitudinal development of hadronic showers in water and ice for energies up to 100 EeV. We present results of a hybrid Monte Carlo method developed for the purpose of simulating those showers. We show parameterizations of the longitudinal development of hadronic showers in ice and we investigate the implications of the LPM effect on shower development. The results obtained are relevant for the detection of high energy cosmic rays and neutrinos in large scale detectors that use water as Cherenkov medium.
