In particle physics, a meson ( / ˈmiːzɒn, ˈmɛzɒn /) is a type of hadronic subatomic particle composed of an equal number of quarks and antiquarks, usually one of each, bound together by the strong interaction. Because mesons are composed of quark subparticles, they have a meaningful physical size, a diameter of roughly one ... Oct 21, 2018 · Now I do understand that there could be Baryons made up of four quarks, and they could have then -1/4 and 3/4 charge of the electron's elementary charge. This would work too, and the neutron and proton would have the same way an integer of the electron's charge. So the atom would be stable. We could do this with any integer number of quarks. We would like to show you a description here but the site won't allow us.Table 5.1: Known quark avors Quarks have an additional attribute, analogous to but di erent from electric charge, which is termed color charge. The color charge of a quark can have three possible values which may be denoted as ‘red’, ‘green’, or ‘blue’. These names are simply labels for di erent quantum states of the quark.1Quark model of nucleon magnetic moments.
