We treat high-energy neutrino production in gamma ray bursts (GRBs). Detailed calculations of photomeson neutrino production are presented for the collapsar model, where internal nonthermal synchrotron radiation is the primary target photon field, and the supranova model, where external pulsar-wind synchrotron radiation provides important additional target photons. Detection of greater, similar 10 TeV neutrinos from GRBs with Doppler factors > or approximately 200, inferred from gamma-ray observations, would support the supranova model. Detection of < or approximately 10 TeV neutrinos is possible for neutrinos formed from nuclear production. Only the most powerful bursts at fluence levels > or approximately 3 x 10(-4) erg cm(-2) offer a realistic prospect for detection of nu(mu).
我们研究伽马射线暴（GRBs）中高能中微子的产生。针对坍缩星模型（其中内部非热同步辐射是主要的靶光子场）和超新星模型（其中外部脉冲星风同步辐射提供重要的额外靶光子），给出了光介子中微子产生的详细计算。从伽马射线观测推断，探测到来自多普勒因子大于或约为200的GRBs的能量更高、类似10 TeV的中微子，将支持超新星模型。对于由核反应产生的中微子，有可能探测到小于或约为10 TeV的中微子。只有通量水平大于或约为3×10⁻⁴ erg cm⁻²的最强大爆发，才为探测μ子中微子提供了现实的前景。
