The forward particle production in the energy range of 1 PeV as seen with the Tibet hybrid Experiment


Abstract:

We are now operating the 500 m2 Yangbajing air-shower core (YAC-II) array near the center of the Tibet air-shower array ( Tibet-III ) to observe cosmic-ray chemical composition at the knee energy region since February 2011. The first step of YAC, called YAC-I, containing 16 detector units, was operated from May, 2009 to February, 2010. In this paper, we used the YAC-I and Tibet-III coincident data set obtained from May, 2009 through January, 2010 to present the electromagnetic spectrum of air shower cores at around 10 15 eV energy region. The effective live time is calculated as 100.5 days. We would like to report the comparison of our experimental data with MC model pbkp_rediction in this paper.
