Borexino实验结果

Results from the Borexino Experiment

Timo Lewke

摘要:

Borexino是位于意大利LNGS地下实验室的太阳中微子低阈值液体闪烁体探测器。由于超高的射电纯度,这是第一个能够对低能太阳中微子进行实时分析的实验。在192天的寿命测量中,太阳7 Be中微子的探测率为47 ± 7计数/天/100吨。在246个生存日后,观测到8B中微子的速率为0.26 ± 0.06个/日/100吨。在MSW-LMA振荡解的情况下,所有探测到的中微子通量都与SSM的预言一致。Borexino是第一个能够同时测量真空主导和物质增强能区太阳中微子振荡的实验。

英文摘要:

Borexino is a low threshold liquid-scintillator detector for solar neutrinos located in the LNGS underground laboratory, Italy. Because of the ultra-high radio purity it is the first experiment able to do a real time analysis of the low energetic solar neutrinos. A detection of the solar 7Be neutrinos with a rate of 47+-7 counts/day/100tons can be reported (192 days of live time measurement). 8B neutrinos are observed with a rate of 0.26+-0.06 counts/day/100tons after 246 live days. All detected neutrino fluxes agree with the SSM predictions in case of the MSW-LMA oscillation solution. Borexino is the first experiment with the ablility to simultaneously measure solar neutrino oscillation in the vacuum-dominated and the matter-enhanced energy regions.
