The total charge of a hadron is equal to the sum of the charges of its constituent's quarks (Fig. 1.23). Quarks come in six categories (names): d, u, s, c, b, and t. Quarks have an additionally character, which is whimsically called color; however, they are of course not really colored. Quark …

and the sum extends over all the leptons and quarks (ψi = e, µ, τ, νe, νµ, ντ , u, d, c, s, b, t), and where Qi is the charge of ψi. Weak Interactions. In contrast to the

Quarks. Quarks and Leptons are the building blocks which build up matter, i.e., they are seen as the "elementary particles". In the present standard model, there are six "flavors" of quarks. They can successfully account for all known mesons and baryons (over 200). The most familiar baryons are the proton and neutron, which are each constructed from up and down quarks.

Like all quarks, the charm quark is an elementary fermion with spin 1 / 2, and experiences all four fundamental interactions: gravitation, electromagnetism, weak interactions, and strong interactions.

Down, strange and bottom are negatively charged, and up, charm and top are positively charged. Particles that contain quarks, like protons and neutrons, are known as hadrons. In a sentence. Quarks usually come in pairs or triplets to make up a bigger particle, but scientists found one unusual quark quartet.

There are: up, down, strange, anti up, anti down and anti strange quarks.When Kaons decayed, scientists observed that the particle took Soon thereafter, a third charged lepton, the tau lepton, was discovered.

If your only requirement is that your theory be free from anomalies, you can have different generations have different charges. If you require that this theory match reality - such as the difference between the lepton and neutrino charges be exactly the same as the W charge - that's a different kettle of fish.

Scaffolded Quark Puzzle Activity - Answers Each piece is a model that represents a tiny particle that is too small to see, called a ^quark _.Every quark has a flavour, an electric charge and a colour charge.

During the strike organized by Rom's Guild of Restaurant and Casino Employees in 2372, Captain Sisko threatened to bill Quark for five years' worth of these outstanding charges unless he agreed to talk to his brother and hammer out an agreement.

These are the up quark, with a charge of + 2/ 3e, and the down quark, which has a charge of − 1/ 3e. The proton consists of two up quarks and one down quark, which gives it a total charge of + e.
