What happens when a quark meets an antiquark?

Antiquarks are the antimatter partners of quarks; they have the same masses as, but the opposite charge from, the corresponding quarks. When a quark meets an antiquark, they may annihilate, disappearing to give some other form of energy.

Are all quarks strange and charm?

A quark (/kwɔːrk, kwɑːrk/) is a type of elementary particle and a fundamental constituent of matter. There are six types, known as flavors, of quarks: up, down, charm, strange, top, and bottom. Up and down quarks have the lowest masses of all quarks.

Can charm decay to up?

The charm quark can only decay via weak decays, mediated by a W±-boson, into a strange or down quark. Thus, open charm particles are the only ones allowing the study of weak decays of an up-type quark in a bound state.

Can a strange quark decay into an up quark?

The top quark is the heaviest of the known fundamental particles. According to the Standard Model, the top quark immediately and almost always decays to a b-quark and a W boson. However, some new physics models predict that decays to either an up or charm quark together with a Z boson (t → uZ or t → cZ) can also occur.

Why do quarks have Colour?

We say quarks have colour, as @Qmechanic points out, because there are some baryons which are composed of 3 identical quarks (in the same spin state) like the Δ++ which is made of 3 u quarks, so the Pauli principle requires another quantum numbers with (at least) 3 values.

What binds matter together?

Gravity is the force that all objects with mass exert upon one another, pulling the objects closer together. The tiny particles that make up matter, such as atoms and subatomic particles, also exert forces on one another.

What is a charm quark in physics?

“Charm (physics)” redirects here. For other uses, see Charm (disambiguation) § Science and technology. The charm quark, charmed quark or c quark (from its symbol, c) is the third most massive of all quarks, a type of elementary particle. Charm quarks are found in hadrons, which are subatomic particles made of quarks.

Which of the following hadrons contain charm quarks?

Some of the hadrons containing charm quarks include: D mesons contain a charm quark (or its antiparticle) and an up or down quark. D. s mesons contain a charm quark and a strange quark. There are many charmonium states, for example the. J/ψ. particle. These consist of a charm quark and its antiparticle.

How can a quark be converted into a different quark?

A quark of one flavor can transform into a quark of another flavor only through the weak interaction, one of the four fundamental interactions in particle physics. By absorbing or emitting a W boson, any up-type quark (up, charm, and top quarks) can change into any down-type quark (down, strange,…

What is the color charge of a quark with an antiquark?

A quark, which will have a single color value, can form a bound system with an antiquark carrying the corresponding anticolor. The result of two attracting quarks will be color neutrality: a quark with color charge ξ plus an antiquark with color charge − ξ will result in a color charge of 0 (or “white” color)…
