What exactly is a quark? What does it do?

It is a subatomic particle, the most basic particle known at present, and the various hadrons we are familiar with are composed of quarks.

Quarks have six "flavors": upper quark up (U), lower quark down (d), strange quark (s) (strange substance with singular numbers), charm quark (c) (with the number of quarks), top quark top (t), bottom quark bottom (b), quarks also have three "colors": red, green, and blue.

Hadrons are made up of them and the glues that stick to them. So there are 18 quarks, and the corresponding 18 antiquarks. Hadron is made up of 3 quarks, which are red, green, and blue in color, and together they become colorless.

The meson is a bound state composed of two quarks of the same color and different tastes, and if they have the same color and taste, they will be annihilated. For example, + consists of an upper quark and an anti-lower quark, and - is the opposite. Each quark has a charge charge of +2 3 or -1 3, specifically:

Upper quark +2 3, lower quark -1 3, odd quark -1 3, charm quark (Cang quark) +2 3, top quark +2 3, bottom quark -1 3. The original theory of strongly interacting particles required three types of quarks, upper quarks, lower quarks, and odd quarks. The discovery of the J particle in 1974 required the introduction of a fourth type of quark (the quintessential quark), the discovery of the Y particle in 1977 required the introduction of a fifth type of bottom quark, and the discovery of a sixth type of quark top quark in 1994, which is believed to be the last type of quark.

The four quarks at the top and bottom of the Wonder are too massive (the mass of the top quark is more than some atoms), and they will soon decay into two quarks, the upper and the lower.

Quarks are particles that make up protons and neutrons.

, the heavier quark quickly turns into an upquark or a downquark through a process called particle decay. Particle decay can turn a high-quality state into a low-mass state, so quarks are very stable.

Quarks have many different intrinsic properties, including electric charge, color charge, spin, and mass. in the standard model.

quarks are the only elementary particles that can withstand all four fundamental interactions.

Fundamental interactions are sometimes referred to as "fundamental forces."

The word "quark" is Gell-Mann from James Joyce.

The phrase taken from "Three quarks for a set marker" in "Finnegan's Wake". This means that there are three quarks in one proton.

Also, quarks have many meanings in this book, and one of the protons consisting of two upper quarks and one lower quark is the call of a seabird. He argues that this suits him when he was originally "elementary particles are not fundamental, elementary charges.

not an integer". At the same time, he also pointed out that it was just a joke and a rebellion against the pretentious language of science. Also, probably because of his love for birds.

Quarks act as the units that make up the nucleus of an atom, and heavier quarks quickly turn into upper or lower quarks through a process called particle decay. Particle decay can turn a high-mass state into a low-mass state, so quarks are stable.

Quarks have a variety of intrinsic properties, including electric charge, color charge, spin, and mass. In the Standard Model, quarks are the only elementary particles that can withstand all four fundamental interactions, which are sometimes referred to as "fundamental forces."

Quarks are the basic units that make up hadrons (including most particles such as neutrons, protons, nucleons, hypertons, baryons, and mesons).

Neutrons, protons, and mesons are composed of more basic units - quarks (neutrons and protons are made up of three quarks, which are baryons, and mesons are composed of two quarks), and many Chinese physicists call quarks "stratons".

Three generations of quark diagrams.

The trichromatic quarks are composed of different baryon nucleons and hyperons (red, blue, and green occupy one color), and the positive and negative quarks form various mesons.

The number in the figure represents the smallest unit of indivisible positive and negative electromagnetic information - qubits (Qubit) (name physicist John. John Wheeler famously said, "It from bit."

After the development of quantum information research, this concept was sublimated to the point that everything originates from qubits) Note: Bits are bits.

Quarks are smaller physical quantities in physics that study molecules and atoms, and it studies particles of more microscopic objects.
