Muons in showers with energy E 0 geq 5 EeV and QGSjetII-04 and EPOS LHC models of hadronic interactions Is there a muon deficit in the models? by Stanislav Knurenko et al. on Monday 28 November The paper presents data on the muon component with a threshold \(\varepsilon_{thr} \geq\) 1 GeV. Air showers were registered at the Yakutsk array during almost 50 years of continuous air shower observations. The characteristics of muons are compared with calculations of QGSjetII-04 and EPOS LHC models for a proton and an iron nucleus. There is a muon deficit in the models, at energies greater than 5 EeV. To make an agreement between experimental data and simulations on muons, further tuning of the models is required. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2208.00606v3
