Study on the primary mass sensitivity of muon multiplicity measured with (YAC-II +Tibet-III + MD) experiment

Abstract:

A new hybrid experiment (YAC-II+Tibet-III+MD) whose installation consists of Tibet air-shower array (Tibet-III, 789 units, 37000 m²), Yangbajing air shower core array (YAC-II, 124 units, 500 m²) and underground water cherenkov muon detector array (MD, 80 units, 5000 m²), has been constructed by the Tibet ASγ collaboration at Tibet, China. The data taking will be started this year. MC air-shower data of each primary component (P, He, CNO, Fe etc) by using various hadronic interaction models (QGSJETII-04, SIBYLL2.1) are obtained by means of a full MC simulation in which the secondary particles of air showers reaching at Yangbajing level are propagated through the (YAC-II+Tibet-III+MD) detector system by using Geant4 (ver. 9.5). Investigating the correlation between the air-shower size (Ne) and the number of muon (Nµ) for different composition, we will report the primary mass sensitivity and interaction model dependence on the muon multiplicity in our (YAC-II+Tibet-III+MD) hybrid experiment.
