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 q...
Trios of quarks make up protons and neutrons (shown), but five quarks together would be extremely unusual.© SPL Physicists have come home empty-handed from a thorough hunting expedition for pentaquarks. The lack of evidence has led some to doubt that these odd subatomic particles, first sigh...

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.
quark, any member of a group of elementary subatomic particles that interact by means of the strong force and are believed to be among the fundamental constituents of matter. Quarks associate with one another via the strong force to make up protons and neutrons, in much the same way that the...

Matter is made of elementary particles, and the Standard Model of particle physics states that these particles occur in two families: leptons (such as electrons and neutrinos) and quarks (which make up protons and neutrons). Under the Standard Model, these two families are totally distinct, with...
Colliding high-energy electrons, and other particles, with protons and neutrons thus gives us insight into the structure of neutrons and protons. Below a certain energy the electrons have a wave-length too large to 'probe' the internal structure of the nucleon and elastic collisions (like those...
both objects look and act like normal neutron stars, except one is too cold and the other is too small. both cases, they said, could be explained if these objects consisted of a dense protoplasm of quarks rather than the agglomeration of neutrons and protons that make up the neutron star....
