地外太阳中微子物理

Extraterrestrial Solar Neutrino Physics

W-Y. Pauchy Hwang, Jen-Chieh Peng

摘要:

我们提倡将地外太阳中微子物理学(etSNP)作为研究太阳中微子物理学(SNP)的一种手段。正如我们已经知道的那样,主振荡和次主振荡(真空)的长度大约是1公里和100公里。另一方面,到目前为止,我们知道物质增强的振荡仅发生在太阳的核心。因此,etSNP,即可以在地球之外提取的太阳中微子物理学,将发挥特殊的独特作用。etSNP实验包括(1)围绕地球或木星或其他行星的卫星(探测器)(为物质增强的中微子振荡提供阴影),(2)在太阳-金星-地球食或类似期间,以及(3)地质类型的化学成分(如在木星或金星中,研究这些行星的起源)。具体地说,我们注意到,由于太阳中微子的唯一高能性质(E_v ^{max}=14.03 MeV),由^8B太阳中微子引起的反应在太阳环境中将是最有趣的。此外,诸如地质类型(金星或木星)的化学成分和日-金星-地食或日-水星-地食时的物质增强振荡等实验也可能是有趣的。

英文摘要:

We advocate the extraterrestrial solar neutrino physics (etSNP) as a means of investigating solar neutrino physics (SNP). As we already know, the dominant and subdominant (vacuum) oscillation lengths would be approximately one kilometer and one hundred kilometers. On the other hand, we know so far that the matter-enhanced oscillations take place only in the core of the Sun. Thus, the etSNP, i.e. solar neutrino physics that could be extracted outside the Earth, would assume a special unique role. The etSNP experiments include (1) a satellite (detector) around the Earth or around the Jupiter or others (to provide the shadow, for the matter-enhanced neutrino oscillations), (2) during the Sun-Venus-Earth eclipse or similar, and (3) the chemical compositions of the geology type (as in the Jupiter or in the Venus, to study the origins of these planets). To be specific, we note that the reactions induced by the ^8B solar neutrinos, in view of the sole high energy nature (E_ν^{max}=14.03 MeV), would be most interesting in the solar environment. Moreover, the experiments such as the chemical compositions of the geology type (on the Venus or Jupiter) and the matter-enhanced oscillations when the Sun-Venus-Earth eclipse, or the Sun-Mercury-Earth eclipse, may also be interesting.
