不幸的是，强子，比如质子和反质子，是由名为夸克的更小单元所组成的。

Unfortunately hadrons, such as protons and antiprotons, are made of smaller bits called quarks.

而K中介子能被任何质子衰变探测仪探测到，比如日本的超级神冈探测器(精度最高)。

And that kaon could be detected by any machine looking for proton decays, namely Japan's SuperKamiokande detector (pictured top).

比如说，当红线在CERN被测量的时候，所有的质子都被包含在了时间剖面里。

For example, at CERN where the red line is measured, all the protons are included in the time profile.
