Generated by EHE meta project with revision 44789. Based on 20k events. The CMC project was responsible for the LPM calculation. Primary particles thrown to the IceCube volume are electron neutrinos

Event Examples

Because the major energy range (~ 1 EeV) of the GZK events does not show sizable lonitudinal elongation due to the LPM effect, many events look nearly indentical with those without accounting LPM effects. Also note that the line-fit based geometrical reconstrution does not work good even to superhigh energy (~ 10EeV) events with streached out longitudinal profile, which results in no improvement of the GZK sensitivity.

Energy: 0.72 EeV NPE: 1.48 e6 Cos(Zenith (MC truth)) : -0.2766 Cos(Zenith (First Gs)) : -0.4174

Energy: 1.32 EeV NPE: 1.09 e6 Cos(Zenith (MC truth)) : -0.2411 Cos(Zenith (First Gs)) : -0.0373

Energy: 8.91 EeV NPE: 2.88 e6 Cos(Zenith (MC truth)) : 0.9110 Cos(Zenith (First Gs)) : 0.6335

Event Distribution Plots

Categorized in the 4 subgroup in the EHE signal cut, from category A (far left) to D. Refer the paper draft for their difinition. No visible change due to the LPM effects is observed. Note that the line-fit based geometrical reconstruction has a trend to give vertical track geometry to the short and poor events passing outside the IceCube volume (i.e. category B and D).
