Description
The measurement of ultra-high energy cosmic rays can only be done
indirectly through the detection of extensive air showers. The
development of such air showers is driven by the interactions of
hadrons in the atmosphere. In order to extract the properties of the
primary cosmic ray from the measurement of the air shower the cascade
of hadron interactions taking place in the atmosphere have to be
modeled. One of the models commonly used for the simulation of the
processes of hadronic multiparticle production in extensive air
showers is SIBYLL.
One aspect of this talk will be the presentation of the development of
the model based on data provided by the LHC experiments. Since the LHC
only covers proton interactions on the order of 10 TeV but
interactions in air showers encompass a much broader range of energies
and projectiles the presentation will further focus on the qualitative
assessment of the remaining uncertainty in the interpretation of the
air shower measurements due to the hadronic models.
