Atmospheric neutrino fluxes

  1. Dec 11, 2012 #1
    Hi I've been asked to give "A physical explanation of why the Θ-dependence of multi-GeV Monte Carlo data is qualitatively different from the sub-GeV data."
    i.e why is the monte carlo simulated data peaked around Cos(theta) = 0 for high energy neutrinos but not low energy ones.

    I'm not sure if i'm going the right way with this.
    I have read that there should be an up down symmetry of neutrino events. But due to the geo magnetic field this is altered for low energy neutrinos. i.e there is an asymetry in the low energy case. This seems to be the right ballpark but i'm not sure where to go next.
    I have some questions:

    1)Cos(zenith angle)= 0
    does this mean horizontal?
    2)If so, why would the high energy flux peak horizontally?
    Any help would be greatly appreciated, I'm stumpted!

    Thanks
