来自天体物理源Charm的高能中微子

High energy neutrinos from charm in astrophysical sources

Rikard Enberg, Mary Hall Reno, Ina Sarcevic

摘要:

粲的产生会从天体物理源中产生非常高能量的中微子流,这些天体物理源具有由中央引擎驱动的喷流,例如伽马射线暴或具有喷流的超新星。粲介子半轻子衰变的中微子通量比π介子和K介子衰变的常规通量受到更少的强子和辐射冷却,因此在更高能量下具有主导贡献,与未来的高能中微子实验有关。

英文摘要:

Charm production gives rise to a flux of very high energy neutrinos from astrophysical sources with jets driven by central engines, such as gamma ray bursts or supernovae with jets. The neutrino flux from semi-leptonic decays of charmed mesons is subject to much less hadronic and radiative cooling than the conventional flux from pion and kaon decays and therefore has a dominant contribution at higher energies, of relevance to future ultrahigh energy neutrino experiments.
