Addressing uncertainties of model predictions for extensive air showers initiated by high energy cosmic rays
Sergey Ostapchenko, Tanguy Pierog, Günter Sigl
A new Monte Carlo generator of hadronic collisions, QGSb, is applied for studying model uncertainties regarding calculations of the development of extensive air showers (EAS) initi…
A basic model for high energy cosmic ray interactions
Sergey Ostapchenko, Tanguy Pierog, Günter Sigl
A Monte Carlo generator of high energy cosmic ray interactions, relying on a very basic and transparent theoretical formalism, in the framework of the Reggeon Field Theory, is pres…
The role of charm and unflavored mesons in prompt atmospheric lepton fluxes
Laksha Pradip Das, Diksha Garg, Maria Vittoria Garzelli +2
The all-sky very-high-energy ( GeV) atmospheric muon flux measured by IceCube shows a spectral hardening at the highest energies, indicating the presence of a prompt com…
Charmed hadron production in the QGSJET-III model: relevance to calculations of the prompt atmospheric neutrino background
Sergey Ostapchenko, Günter Sigl
The treatment of charmed hadron production in the framework of the QGSJET-III Monte Carlo generator is developed, including both perturbative and nonperturbative contributions. For…
On the model uncertainties for the predicted muon content of extensive air showers
Sergey Ostapchenko, Günter Sigl
Motivated by the excess of the muon content of cosmic ray induced extensive air showers (EAS), relative to EAS modeling, observed by the Pierre Auger Observatory, and by the tensio…
On the prompt contribution to the atmospheric neutrino flux
Sergey Ostapchenko, Maria Vittoria Garzelli, Günter Sigl
The prompt contribution to the atmospheric neutrino flux is analyzed. It is demonstrated that the corresponding theoretical uncertainties related to perturbative treatment of charm…
