WebOn the other hand, mesons bosons are composed of two quarks: a quark and an antiquark. Besides charge and spin (1/2 for the baryons), two other quantum numbers are assigned to these particles: baryon number (B) and strangeness (S). Baryons have a baryon number, B, of 1, while their antiparticles, called antibaryons, have a baryon number of −1. WebA baryon made of three quarks will have a spin three times the spin of the electron or proton if the spins are parallel and will have a spin equal to the electron spin if the spin of one is opposite to the spin of the other two.

WebSo to figure out the baryon number of a Xi baryon, we can add together the baryon number of its quarks. Each one has a baryon number of positive one-third, and so they add up to one. This is indeed the baryon number of a Xi baryon. But note that there’s another way that we could’ve gotten the same answer. We could recall that any particle ... WebThe new particle that makes up the Lambda 0 baryon is called a strange quark, and we’ll visit them soon enough.
