Discovery of new sub-atomic particle
This week, NightHawk seems to be focusing on science. Today’s subject is sub-atomic particles, something on which I touched only recently in this posting.
Now it may have escaped your notice – it escaped mine at the time – but earlier this summer scientists issued a statement announcing the discovery of a new sub-atomic particle.
It is known as the “cascade b” and it is made of a ‘down’, a ‘strange’ and a ‘bottom’ quark. It is the first observed baryon formed of quarks from all three families of matter. Its discovery and the measurement of its mass provide new understanding of how the strong nuclear force acts upon the quarks, the basic building blocks of matter.
The “cascade b” fills a missing slot in the Standard Model.
