Non- baryonic matter , as implied by the name, is any sort of matter that is not primarily composed of baryons.
而非重子物质则是从质量上来看主要不是由重子组成的物质，比如中微子、自由电子、光子等等。But how much of a delay between neutrinos and photons would we expect if the OPERA result applied?
但是，如果OPERA的结果适用，我们期望中微子和光子之间的延时能到多大程度？Admittedly, the energy needed to produce a Cepheid-modulating neutrino beam really would be a sizeable fraction of the output of the sun.
应当承认，制造用来调整“造父变星”的中微子束所需要的能量确实将相当于太阳整体输出能量的大部分份额。One of the only exceptions is the theoretical "sterile neutrino" , represented by a closed loop of string.
仅有例外之一是理论上的“惰性中微子（sterileneutrino）”，它由弦的闭合环来表示。The point is to see if they are still muon-neutrinos when they arrive at Super-Kamiokande.
T2K实验的目的是看当它们到达超级神冈探测器的时候，是否仍然是缪子中微子。The thinking goes that WIMPs are very heavy, yet like neutrinos they rarely bump into matter to produce a detectable signal.
理论认为，WIMP粒子非常重，但是又像中微子一样几乎不与其它物质发生相互作用，因此不能产生可观察的信号。As the neutrinos emitted this radiation, they ought to have been losing a commensurate amount of energy.
由于中微子发出了辐射，它们应该失去相对应的能量。A neutrino with this energy has a good chance of producing a particle known as a W- when it passes through a detector.
当这一能级的中微子通过检测器时有很大概率产生一种被称为W-的粒子。Northern-sky neutrinos come streaking upward through the detector, from the bedrock toward the surface of the ice.
来自北部天空的中微子沿着岩层指向冰面的方向高速向上穿过探测器。
