LHCb colliding-beam measurements for astroparticle physics
Measurements of Relevance for Cosmic-Ray Physics with NA61/SHINE
In recent times, the Pythia event generator has been extended to feature simulations of generic hadron-nucleon interactions. In this talk, I present a further extension to hadron-ion interactions, which are of particular relevance for air showers where hadronic cascades interact with nuclei in the air.
The model has been validated against NA61/SHINE data. The model also has applications to...
I shall discuss new theoretical approaches implemented in the QGSJET-III Monte Carlo generator and present selected model results regarding secondary hadron production in hadron-proton and hadron-nucleus collisions. The predictions of the model for basic characteristics of proton-induced extensive air showers (EAS) will be compared to the ones of QGSJET-II and of other cosmic ray interaction...
I discuss the calculations of atmospheric fluxes (prompt and conventional)
and LHC input useful for it.
genealogical studies of EM and hadron/muon EAS component with CORSIKA 8 and comparisons with Heitler-Matthews model
Several high-energy cosmic-ray experiments have observed an excess of muons compared to theoretical expectations from air shower simulations based on standard hadronic interaction models. We investigate the potential of producing states of dense quark-gluon matter (so-called fireballs) to resolve the excess of muons on the ground for a given depth of the shower maximum. Adopting a...
CRPropa 3.2, released recently, is the latest update in a continued effort to maintain and extend this open-source code well known in the cosmic-ray community. Originally aimed at simulating the ballistic propagation and interactions of Ultra-High Energy Cosmic Rays, today it can handle diffusive propagation of cosmic rays in a variety of magnetic fields, deal with stochastic cosmic ray...

A RIVETing journey: Analysis Preservation and Generator Tuning in High Energy Physics
We present the MCPLOTS online resource for MC event-generator validations. The project is based on the RIVET analysis library and harnesses volunteer computing to generate high-statistics MC comparisons to data. Users interact with the resource via a simple web site, mcplots.cern.ch, where run cards, histogram points, etc, are all made easily available for download. The project has been...
Relevance of hybrid data to the tuning of hadronic interaction models
Radio Detection and its relevance for studying air shower physics
Ulrich et al. have shown already in 2011 that changing the cross-section, elasticity and multiplicity of hadronic interactions at very high energies with respect to the standard hadronic interaction models has a direct impact on predicted depths of the shower maxima and numbers of muons at ground. We have expanded this work from the original 1D implementation in CONEX to full 3D simulations in...
This talk provides an introduction into the Ultra-relativistic Quantum Molecular Dynamics model (UrQMD). UrQMD is a well established transport approach to simulate hadron-hadron, hadron+nucleus and nucleus+nucleus reactions at beam energies starting from 1 GeV to center-of-mass energies of a few hundred GeV. UrQMD has been well tested against a wide range of accelerator data for various...
Status of nuclear-PDF analyses and prospects with light ions
Chromo: An event generator frontend for particle and astroparticle physics
LHCf is an LHC experiment designed to study high energy hadronic interaction for understanding cosmic-ray-induced air-shower development. LHCf measures the differential production cross-sections of neutral particles (photons, pi0, and neutrons) at the very forward region of collisions. In this talk, I will review LHCf results and discuss the prospects of ongoing analyses and future operation...
