Description

A long-standing puzzle in cosmic ray physics has been the nature of the spectrum, which is very well modeled by a broken power law with differing exponents, both close to -3, above and below the "knee". We show that a rather simple hadronic evaporation model reproduces the correct exponents, and the location of the knee without free parameters. The model is predictive, with some successful predictions already and has broader implications for nuclear physics and particle astrophysics.
