| 英文摘要 | In this paper, we first calculate the realistic Earth matter effects in the detection of type II supernova neutrinos at the Daya Bay reactor neutrino experiment which is currently under construction. It is found that the Earth matter effects depend on the neutrino incident angle theta, the neutrino mass hierarchy Delta m(31)(2), the crossing probability at the high resonance region inside the supernova, P(H), the neutrino temperature, T(alpha), and the pinching parameter in the neutrino spectrum, eta(alpha). We also take into account the collective effects due to neutrino-neutrino interactions inside the supernova. With the expression for the dependence of P(H) on the neutrino mixing-angle theta(13), we obtain the relations between theta(13) and the event numbers for various reaction channels of supernova neutrinos. Using these relations, we propose a possible method to acquire information about theta(13) smaller than 1.5 degrees. Such a sensitivity cannot be achieved by the reactor neutrino deta at the Daya Bay experiment which has a sensitivity of the order of theta(13)similar to 3 degrees. Furthermore, we apply this method to other neutrino experiments, i.e. Super-K, SNO, KamLAND, LVD, MinBooNE, Borexino, and Double-Chooz. We also study the energy spectra of the differential event numbers, dN/dE. |
