超新星中中微子非标准相互作用的可能踪迹

Possible trace of neutrino nonstandard interactions in the supernova

C. R. Das, Joao Pulido

摘要:

中微子非标准相互作用(NSI),以前介绍了太阳,在超新星的背景下进行了研究。对于正常的层次的概率电子中微子和反中微子在低能量($E\lesssim 0.8-0.9 MeV$)大大增加相对于非NSI的情况下,并加入其值的逆层次是恒定的能量。同样,对于逆层次,每个中微子和反中微子种类的NSI和非NSI概率是相同的。这些是超新星中NSI可能的可见效应。由于反中微子产生的几率很小,所以在实验上无法看到衰变为反中微子的过程,而这一过程之前已经被证明是由致密物质所暗示的。

英文摘要:

Neutrino non-standard interactions (NSI), previously introduced for the sun, are studied in the supernova context. For normal hierarchy the probability for electron neutrinos and antineutrinos at low energy ($E\lesssim 0.8-0.9 MeV$) is substantially increased with respect to the non-NSI case and joins its value for inverse hierarchy which is constant with energy. Also for inverse hierarchy the NSI and non-NSI probabilities are the same for each neutrino and antineutrino species. These are the possible visible effects of NSI in the supernova. The decay into antineutrinos, which has been previously shown to be implied by dense matter, cannot be seen experimentally, owing to the smallness of the antineutrino production probability.
