标题： Limits on the Transient Ultra-High Energy Neutrino Flux from Gamma-Ray Bursts (GRB) Derived from RICE Data

摘要： 我们根据RICE实验最近提供的数据、限制和模拟，给出了对超高能（UHE；E(nu)>1 PeV）中微子通量的限制。 我们使用了五次记录的瞬变事件的数据，这些事件具有足够的光子能谱形状和红移信息，以推导出预期的中微子通量，假设观测到的光子通过π介子衰减与中微子产生相关联，这是众所周知的“Waxman-Bahcall”方法。 了解观测到的爆发的赤纬，以及RICE在极角函数下的灵敏度，以及之前发布的未观测到任何中微子事件的结果，可以估计对给定中微子通量的灵敏度。 尽管比预期的通量弱几个数量级，但我们的GRB中微子通量限制仍然是在PeV-EeV能量范围内的首次限制。 为了完整性，我们还提供了其他爆发的列表，在RICE实验运行期间记录的爆发，但需要一些关于光度和红移的假设才能估计中微子通量。 显示英文摘要

摘要： We present limits on ultra-high energy (UHE; E(nu)>1 PeV) neutrino fluxes from gamma-ray bursts (GRBs), based on recently presented data, limits, and simulations from the RICE experiment. We use data from five recorded transients with sufficient photon spectral shape and redshift information to derive an expected neutrino flux, assuming that the observed photons are linked to neutrino production through pion decay via the well-known 'Waxman-Bahcall' prescription. Knowing the declination of the observed burst, as well as the RICE sensitivity as a function of polar angle and the previously published non-observation of any neutrino events allows an estimate of the sensitivity to a given neutrino flux. Although several orders of magnitude weaker than the expected fluxes, our GRB neutrino flux limits are nevertheless the first in the PeV--EeV energy regime. For completeness, we also provide a listing of other bursts, recorded at times when the RICE experiment was active, but requiring some assumptions regarding luminosity and redshift to permit estimates of the neutrino flux.
