| 英文摘要 | We analyzed the evolution data of the daya bay reactor neutrino experiment in terms of short-baseline active-sterile neutrino oscillations taking into account the theoretical uncertainties of the reactor antineutrino fluxes. we found that oscillations are disfavored at 2.6 sigma with respect to a suppression of the u-235 reactor antineutrino flux and at 2.5 sigma with respect to variations of the u-235 and pu-239 fluxes. on the other hand, the analysis of the rates of the short-baseline reactor neutrino experiments favor active-sterile neutrino oscillations and disfavor the suppression of the u-235 flux at 3.1 sigma and variations of the u-235 and pu-239 fluxes at 2.8 sigma. we also found that both the daya bay evolution data and the global rate data are well-fitted with composite hypotheses including variations of the u-235 or pu-239 fluxes in addition to active-sterile neutrino oscillations. a combined analysis of the daya bay evolution data and the global rate data shows a slight preference for oscillations with respect to variations of the u-235 and pu-239 fluxes. however, the best fits of the combined data are given by the composite models, with a preference for the model with an enhancement of the pu-239 flux and relatively large oscillations. |
