Quarks are one of the basic building blocks of matter, making up the protons and neutrons that are found in the nuclei of atoms. But a new model suggests that these subatomic particles may not be so fundamental after all, but instead just a quantum illusion. ...

The meaning of QUARK is any of several elementary particles that are postulated to come in pairs (as in the up and down varieties) of similar mass with one member having a charge of +2/3 and the other a charge of —1/3 and are held to make up hadrons.
Quarks——介绍夸克的英文资料-推荐下载
Quarks make upprotons and neutrons, which, in turn, make up an atom's nucleus. Each proton and each neutron contains three quarks. A quark is a fast-moving point of energy. Do quarks have mass? Quarks have anastonishingly wide range of masses. ... According to their results, the up ...

Baryon, any member of one of two classes of hadrons (particles built from quarks and thus experiencing the strong nuclear force). Baryons are heavy subatomic particles that are made up of three quarks. Both protons and neutrons, as well as other particle
