Hadronic interaction and EAS muon investigated with the (YAC-II+Tibet-III+MD) hybrid experiment


Abstract:

The Tibet hybrid experiment (Tibet-III+YAC+MD) consists of YAC (Yangbajing Air shower Core detector array), the Tibet-III air-shower array and the water-Cherenkov-type Muon Detector array (MD). The first step of YAC, called YAC-I that consists of 16 EAS core detectors located near the center of the Tibet-III, has been carried out since May, 2009. For the coincident events, Tibet-III provides the total energy and the direction of air showers and YAC-I observes high energy electromagnetic particles in the air-shower core region.We will operate MD this year to record the number of muons produced in air showers. In this paper, we will report on the check of hadronic interaction models (QGSJETII-04, EPOS LHC(v3400), SIBYLL2.1) at primary energy region around 1 PeV by observing EAS cores using (YAC-I+Tibet-III) hybrid experimental data.The effective live time is calculated as 128.6 days. Furthermore, we discuss about EAS muon multiplicity with the (Tibet-III+YAC+MD) data.
