quark - (physics) hypothetical truly fundamental particle in mesons and baryons; there are supposed to be six flavors of quarks (and their antiquarks), which come in pairs; each has an electric charge of +2/3 or -1/3; "quarks have not been observed directly but theoretical predictions based on their existence have been confirmed experimentally"

Objective: This proposal plans to develop simulations of heavy quark phenomenology in2+1f QCD with the vacuum effects of up, down and strange quarks simulated directlyat physical quark masses.
It is "strange" because its supply of dense matter is composed primarily of strange quarks, which would represent a stage of collapse even denser than that characterizing a neutron star.
Physicists use a more complex, three-dimensional chart to also convey information on the number of neutrons, which may change in different isotopes of the same element, and a quantum number known as "strangeness," which depends on the presence of strange quarks.
The standard model of particle physics predicts the existence and mass of this particle, which is a baryon, like protons and neutrons, and is made up of two strange quarks and a bottom quark.
The strange matter is a ultra-dense matter formed by a big number of strange quarks bounded together with an electron atmosphere (this strange matter is hypothetical).
There is no clear subprocess which seems to dominate the total amplitude, but there is speculation that strange quarks [15] and sea quarks [16] play an important role.
Proton's cousin Physicists discover omega-b-minus, a particle made of two strange quarks and a bottom quark (SN: 9/27/08, p.
There are six types: up, down, beauty, truth, charm, and strange quarks.
The new particle, long predicted to exist, is made of a bottom quark--the second-heaviest of all quarks--with two, much lighter strange quarks essentially orbiting around it, says Fermilab physicist Dmitri Denisov.
The quark matter would consist not only of the up and down quarks that make up protons and neutrons, but also strange quarks, which aren't found in ordinary matter.
