论文摘要
我们讨论通过搜索中微子从最明亮的伽马射线爆发（GRB 221009a）中获得的含义。考虑到中微子光谱和有效区域，我们对GRB模型参数（例如宇宙射线载荷因子和耗散半径）产生了限制。结果足以限制光球附近的质子加速度，我们发现单个爆发极限与堆叠分析相当。来自次光圈和外部冲击的超高能中微子的quasithermal中微子尚未受到限制。我们表明，源自中子碰撞的GEV-TEV中微子是可以检测到的，并敦促对这些中微子的专用分析，并使用深核和IceCube以及ORCA和KM3NET。
We discuss implications that can be obtained by searches for neutrinos from the brightest gamma-ray burst, GRB 221009A. We derive constraints on GRB model parameters such as the cosmic-ray loading factor and dissipation radius, taking into account both neutrino spectra and effective areas. The results are strong enough to constrain proton acceleration near the photosphere, and we find that the single burst limits are comparable to those from stacking analysis. Quasithermal neutrinos from subphotospheres and ultrahigh-energy neutrinos from external shocks are not yet constrained. We show that GeV-TeV neutrinos originating from neutron collisions are detectable, and urge dedicated analysis on these neutrinos with DeepCore and IceCube as well as ORCA and KM3NeT.
