Baryons
All particles can be classified into two broad categories: leptons and hadrons. The main difference between the two is whether they interact through the strong interaction. Hadrons are particles that interact through all four fundamental interactions of nature, which include, strong, electromagnetic, weak, and gravitational interactions. Hadrons, the strongly interacting particles, can be further subdivided into two classes based on their internal composition: mesons and baryons. Originally, mesons and baryons were classified according to their masses. Baryons were heavier than mesons, and both were heavier than leptons. Today mesons and baryons are distinguished by their internal structure. Baryons have masses greater than the proton mass. All hadrons are composed of two or three fundamental particles, which came to be known as quarks. A quark is always combined with one or two other quarks. According to the original model proposed by Murray Gell-Mann and George Zweig in 1963, there were three types of quarks indicated by the symbols u, d, and s. These were given the arbitrary names up, down, and sideways (now referred to as strange). Associated with each quark is an anti-quark, which are the antimatter equivalents
In general, only a small part of the mass of a hadron (such as a proton) is due to the rest mass of the quarks in it. The Standard Model is the combination of two theories of particle physics into a single framework to describe all interactions of subatomic particles, except those due to gravity. The total charge of the proton is +e. An important property of baryons is it mass. The rule you need to remember for baryons is that they are always made from 3 quarks. Physicists hope that, by probing the standard model in detail and making highly accurate measurements, they will discover some way in which the model begins to break down and thereby find a more complete theory. We are seeing only the conceptual results of this very mathematical theory, but we should realize that is it based on experimental evidence. It makes no predictions of the masses of the quarks and the leptons neither of the strengths of the various interactions. In addition to these force-carrying particles, the standard model includes two families of subatomic particles that build up matter and that have spins of one-half unit. These particles are the quarks and the leptons, and there are six varieties, or "flavors," of each, related in pairs in three "generations" of increasing mass. The total charge of quarks in a neutron is zero. The neutron's mass is slightly higher, at 1,839 times the electron mass. The three-color charges are labeled in accordance with the three primary colors RED, GREEN, and BLUE. Yet it has a number of weaknesses that lead physicists to search for a more complete theory of subatomic particles and their interactions.
