New version of the hadronic interaction model Sibyll
Sibyll is one of the hadronic event generators commonly used in the simulation of extensive air showers. Since the last release, which dates back to the TeVatron era, modeling of hadronic interactions has seen development in several directions. For one the high energy frontier has been significantly moved up by the LHC, revealing discrepancies in the prediction of the total cross section, the role of multi parton interactions and overall particle production. At the same time the apparent deficit of muons in cosmic ray air shower simulations with regard to observations, revealed the misrepresentation of hadronic particle production in the model. Finally the measurement of high energy neutrinos by the IceCube experiment add the prompt production of neutrinos through charmed decays as a necessary feature of cosmic ray interaction models.
