Abstract

The correlation between the data obtained with two gravitational wave (GW) detectors (in Rome and in Maryland) and two neutrino detectors (LSD in Italy and Kamiokande in Japan) has been studied in more detail. If we indicate with U1 the response of the gravitational wave detectors and with U2 the response of the neutrino detectors, we find that there is a clear time correlation between U1 and U2: namely U2 comes later than U1 by an amount depending on the energy measured in the neutrino detectors (the delay decreases with the detected neutrino energy). A straightforward calculation would yield a mass for the U2 particles between 4 and 6 eV. If one further assumes that the U2 is due to neutrinos whose mass has been evaluated to be less than 0.1 eV (at 90% c.l.), we hazard the idea that a slow down during the neutrinos’ 168 000 light-year travel from SN1987A to Earth could be inferred.

引力波与中微子探测器的相关性:来自SN1987A的长中微子航程

摘要

对使用两个重力波(GW)探测器(在罗马和马里兰)和两个中微子探测器(意大利的LSD和日本的Kamiokande)获得的数据之间的相关性进行了更详细的研究。如果我们用U1表示引力波探测器的响应,而用U2表示中微子探测器的响应,我们发现U1和U2之间存在明显的时间相关性:即U2比U1晚一些,具体取决于测得的能量在中微子检测器中(延迟随着检测到的中微子能量而减小)。直接计算将得出U2粒子的质量在4到6 eV之间。如果进一步假设U2是由于中微子引起的,中微子的质量已评估为小于0.1 eV(在90%cl时),
