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…

Road map for the tuning of hadronic interaction models with accelerator-based and astroparticle data

Johannes Albrecht, Julia Becker Tjus, Noah Behling +52

In high-energy and astroparticle physics, event generators play an essential role, even in the simplest data analyses. As analysis techniques become more sophisticated, e.g. based…

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…

Prompt atmospheric leptons and the potential role of intrinsic charm

Laksha Pradip Das, Diksha Garg, Maria Vittoria Garzelli +2

The all-sky very-high energy ( GeV) atmospheric muon flux is most recently measured by IceCube, where in the higher energy range, the spectrum hardens indicating a promp…
