The IceCube Collaboration initially reported the detection of 37 extraterrestrial neutrinos in the TeV–PeV energy range. The reconstructed neutrino events were obtained during three consecutive years of data taking, from 2010 to 2013. Although these events have been discussed to have an extragalactic origin, they have not been correlated to any known source. Recently, the IceCube Collaboration reported a neutrino-induced muon event with energy of $2.6\pm 0.3$ PeV which corresponds to the highest event ever detected. Neither the reconstructed direction of this event (J2000.0), detected on June 11 2014 at $\text{R.A.}=110\mathrm{°}.34$, $\text{Dec.}=11\mathrm{°}.48$ matches with any familiar source. Long gamma-ray bursts (lGRBs) are usually associated with the core collapse of massive stars leading relativistic-collimated jets inside stars with high-energy neutrino production. These neutrinos have been linked to the 37 events previously detected by IceCube experiment. In this work, we explore the conditions and values of parameters so that the highest neutrino recently detected could be generated by proton–photon and proton–hadron interactions at internal shocks inside lGRB progenitor star and then detected in IceCube experiment. Considering that internal shocks take place in a relativistic collimated jet, whose (half) opening angle is ${\theta }_0\sim 0.1$, we found that lGRBs with total luminosity $L\lesssim {10}^{48}$ erg/s and internal shocks on the surface of progenitors such as Wolf–Rayet (WR) and blue super giant (BSG) stars favor this multi-PeV neutrino production, although this neutrino could be associated with $L\sim {10}^{50.5}$ ($\sim {10}^{50}$) erg/s provided that the internal shocks occur at $\sim {10}^9$ $(\sim {10}^{10.2})\text{cm}$ for a WR (BSG).

IceCube协作组织最初报告在TeV–PeV能量范围内检测到37个地外中微子。从2010年到2013年，在连续三年的数据采集中获得了重建的中微子事件。尽管已经讨论了这些事件具有银河外起源，但它们与任何已知来源均不相关。最近，IceCube协作组织报告了中微子引起的μ子事件，其能量为$2.6\pm 0.3$PeV对应于有史以来检测到的最高事件。2014年6月11日，在此事件的重构方向（J2000.0）均未检测到$\text{RA}=110\mathrm{°}。34$， $\text{十二月}=11\mathrm{°}。48$与任何熟悉的来源相匹配。长伽马射线爆发（lGRB）通常与大质量恒星的核心坍塌有关，大质量恒星导致高能中微子产生的恒星内部的相对论准直射流。这些中微子与先前由IceCube实验检测到的37个事件有关。在这项工作中，我们探索了参数的条件和值，以便最近检测到的最高中微子可以由lGRB祖星内部的内部震荡下的质子-光子和质子-强子相互作用产生，然后在IceCube实验中检测到。考虑到内部冲击发生在相对论准直射流中，其（半）开角为${\theta }_0〜0.1$，我们发现具有总发光度的lGRB $\mathrm{大号}\lesssim {10}^{48}$ erg / s和沃尔夫·雷耶特（WR）和蓝色超巨星（BSG）等祖先表面的内部震荡都有利于这种多PeV中微子的产生，尽管这种中微子可能与 $\mathrm{大号}〜{10}^{50.5}$ （$〜{10}^{50}$）erg / s，前提是内部震动发生在 $〜{10}^9$ $（〜{10}^{10.2}）\text{厘米}$ WR（BSG）。
