The strong force, which we generally call the nuclear force, is actually the force that binds quarks together to form baryons (3 quarks) and mesons (a quark and an anti-quark). The nucleons of everyday matter, neutrons and protons, consist of the quark combinations uud and udd, respectively.

16 Απρ 2024 · Thus, in quantum chromodynamics (QCD), quantum loop corrections affect the gluon’s behavior and determine how much α s changes with the distance between quarks. With this new distance dependence...
10 Νοε 2024 · The strong force binds quarks together within protons, neutrons, and other subatomic particles. Rather as the electromagnetic force is ultimately responsible for holding bulk matter together, so the strong force also keeps protons and neutrons together within atomic nuclei.
These forces describe the movement of galaxies, the chemical reactions in our laboratories, the structure within atomic nuclei, and the cause of radioactive decay. They describe the true cause behind familiar terms like friction and the normal force.
We just make all possible combinations of a quark and antiquark, apart from the scalar one \(\eta'=u\bar{u}+d\bar{d} +c\bar{c}\) (why?). Figure \(\PageIndex{2}\): quark assignment of the meson octet A similar assignment can be made for the nucleon octet, and the nucleon decaplet, see e.g., see FFigure \(\PageIndex{3}\).
3 Απρ 2014 · The variation in friction force was found for a wide range of normal forces, from negative to strongly positive, and it was observed for all sliding directions with respect to the lattice of the graphite substrate (and that of the graphite flake on the tip) .
most fundamental particles and forces, explaining how they fit together to form larger, more complex structures. Protons, for example, are made up of three elementary particles named quarks, which are held together by the strong nuclear force. The strong nuclear force is itself mediated by massless particles called gluons.
