Testing of the VENUS 4.12, DPMJET 2.55, QGSJET II-03 and SIBYLL 2.3 hadronic interaction models via help of the atmospheric vertical muon spectra

Abstract

Abstract.Uncertainties of the model energy spectra of the most energetic secondary π ± -mesons (and K ± -mesons) are discussed. Computer simulations of the partial energy spectra of the atmospheric vertical muons induced by primary cosmic particles with various fixed energies in interval 10 2 −10 7 GeV in terms of the VENUS 4.12, DPMJET 2.55, QGSJET II-03 and SIBYLL 2.3 models had been carried out with help of CORSIKA package. These partial spectra should be convoluted with the contemporary spectra of the primary cosmic particles. Results of simulations are compared with the contemporary atmospheric vertical muon flux data. Comparison shows that all models underestimate production of secondary π ± -mesons (and K ± -mesons) by factor of ∼ 2 at the most high energies. This underestimation induces more rapid development of extensive air showers in the atmosphere and results in uncertainties in estimates of energy and composition of the primary cosmic particles.

Testing of almost all the hadronic interaction models by comparing calculated muon energy spectrum with data

“…In this paper the muon fluxes intensities for the DPM-JET 2.55, QGSJET II-03, SIBYLL 2.3 and VENUS 4.12 models differ by ∼ 2 ÷ 15% with an increase in energy from ∼ 10 2 GeV to ∼ 10 4 GeV compared with the work of Ref. [42,43] due to slightly different modified approximations of the primary cosmic ray spectrum.…”

“…The main conclusion is quite clear. All considered models demonstrate the valuable deficit of muons [39][40][41][42][43].…”
