AbstractSupernova (SN) neutrinos detected on the Earth are subject to the shock wave effects, the Mikheyev-Smirnov-Wolfenstein (MSW) effects, the neutrino collective effects and the Earth matter effects. Considering the recent experimental result about the large mixing angle theta(13) (similar or equal to 8.8 degrees) provided by the Daya Bay Collaboration and applying the available knowledge for the neutrino conversion probability in the high resonance region of SN, P-H, which is in the form of hypergeometric function in the case of large theta(13), we deduce the expression of P-H taking into account the shock wave effects. It is found that P-H is not zero in a certain range of time due to the shock wave effects. After considering all the four physical effects and scanning relevant parameters, we calculate the event numbers of SN neutrinos for the "Garching" distribution of neutrino energy spectrum. From the numerical results, it is found that the behaviors of neutrino event numbers detected on the Earth depend on the neutrino mass hierarchy and neutrino spectrum parameters including the dimensionless pinching parameter B-alpha (where alpha refers to neutrino flavor), the average energy < E-alpha >, and the SN neutrino luminosities L-alpha. Finally, we give the ranges of SN neutrino event numbers that will be detected at the Daya Bay experiment.
