介子和μ子加速引起的阻塞伽马射线暴的高能中微子发射增强

Enhanced high-energy neutrino emission from choked gamma-ray bursts due to meson and muon acceleration

Hylke B. J. Koers, Ralph A. M. J. Wijers

摘要:

有人提出,可能有很大一部分超新星伴随着相对论性外流,在恒星表面以下停滞。在这封信中,我们指出,内部冲击被认为是加速质子到非常高的能量在这些流动也将加速次级介子和μ子。因此,介子和μ子衰变产生的中微子谱预计比以前的估计要难得多,作为一个单一的幂律扩展到~10^3 TeV。这大大改善了检测前景。

英文摘要:

It has been suggested that a potentially large fraction of supernovae could be accompanied by relativistic outflows that stall below the stellar surface. In this letter we point out that internal shocks that are believed to accelerate protons to very high energies in these flows will also accelerate secondary mesons and muons. As a result the neutrino spectrum from meson and muon decay is expected to be much harder compared to previous estimates, extending as a single power law up to ~10^3 TeV. This greatly improves the detection prospects.
