The Hadronic Interaction Workshop

Precise knowledge of high energy hadronic interaction is an important key to understand air shower development. The LHCf experiment measures neutral particles such as photons, neutral pions, and neutrons, produced in the very forward region of LHC collisions, which contribute to the air shower development. Since the LHC start, LHCf performed many operations with pp collisions at several...

I will emphasize the necessity of the soft mode in the small-x formalism for producing correctly the poles and for carrying out resummation.

The goal of a multi-phase transport (AMPT) model is to provide a kinetic theory description of all essential stages of relativistic nuclear collisions. Here I will first introduce the AMPT model including its structure and selected earlier results. I will then discuss the recent puzzle on baryon stopping from RHIC, which affects the yield and rapidity distributions of net-baryons. Finally, I...

This study investigates hadronic interaction models through a detailed analysis of muon content in extensive air showers (EAS) using the LHAASO-KM2A detector. The primary objective is to evaluate the consistency of muon production predictions from three hadronic interaction models (EPOS-LHC, QGSJET-II-04, and SIBYLL 2.3d) and spectral models (Gaisser H3a, Horandel, GSF, and LHAASO spectrum)...

The LHAASO experiment can measure muons and parameters related to the shower maximum in an extensive air shower. These parameters depend on the assumptions of the hadronic interaction model. This study uses parameters measured by LHAASO experiment to test hadronic interaction models. We will present the preliminary results of the testing of the EPOS-LHC and QGSJETII-04 models using the LHAASO...
