Test of the hadronic interaction model EPOS-LHC and QGSJETII-04 with Tibet EAS core data


Abstract:

A hybrid experiment has been started by The Tibet ASγ collaboration at Tibet, China. It consists of a burst-detector-grid (YAC, Yangbajing Air Shower Core array) and the Tibet air-shower array (Tibet-III). The Tibet-III array is used to measure the total energy and the arrival direction of the air-showers, and YAC-I observes high energy electromagnetic particles in air-shower cores. By comparing the MC data with our experimental data, we examine hadronic interaction models currently used for air-shower simulation code CORSIKA(ver.7.3500), especially EPOS-LHC(ver.3400) and QGSJETII-04. In this paper, the preliminary results on the interaction model check at *10 TeV energy region is reported using YAC-I data taken from May 1st 2009 through February 23rd 2010 with the effective live time 152.16 days.
