磁化奇异星的中微子振荡

Neutrino Oscillation from Magnetized Strange Stars

Nissim Fraija, Enrique Moreno Méndez

摘要:

奇异夸克物质(SQM)是核物质基态的一个可能候选者。与许多其他状态方程(EoS)一样,SQM似乎受到最近发现的1.97 $M_\odot$ PSR J1614-2230和2.01 $M_\odot$ PSR J 0348 +0432的严重限制。然而,通过新的$O(α_c^2)$微扰计算,SQM似乎能够容纳像$\sim 2.75 M_\odot$一样大的质量。SQM星或奇异星的文献估计其内部磁场与$10^{20}$ G一样大,但不太可能形成,因为它们需要产生$\sim 10^{57}$ erg。尽管如此,如果奇异恒星可能拥有磁强度场($10^{15}$ G),它们的内部磁场很可能达到与$10^{17}$ G一样大的磁场。我们认为中微子能量的一些兆电子伏和振荡参数从太阳,大气和加速器实验。研究了奇异星中中微子共振振荡的可能性。

英文摘要:

Strange-quark matter (SQM) is a likely candidate of the ground state of nuclear matter. Along with many other equations of state (EoSs), SQM seemed to be severely constrained by the recent discoveries of the 1.97 $M_\odot$ PSR J1614-2230 and the 2.01 $M_\odot$ PSR J0348+0432. However with new, $O(α_c^2)$, perturbative calculations, SQM seems to be able to accommodate masses as large as $\sim 2.75 M_\odot$. The literature of SQM stars or strange stars includes estimates of internal magnetic fields as large as $10^{20}$ G, which are unlikely to be formed as they would require $\sim 10^{57}$ erg to be produced. Nonetheless, if strange stars may hold magnetar-strength fields ($10^{15}$ G), their internal fields are likely to reach magnetic fields as large as $10^{17}$ G. We consider neutrinos with energies of some MeV and oscillation parameters from solar, atmospheric and accelerator experiments. We study the possibility of resonant oscillation of neutrinos in strange stars.
