quark

(qwark),
A fundamental particle believed to be the primary constituent of all mesons and baryons; quarks have a charge that is a fraction of 1 electron charge and interact through electromagnetic and nuclear forces. Six varieties are thought to exist with the unusual names of up, down, strange, charmed, bottom, and top.

At first, they ignored the quarks and antiquarks that popped out of nowhere.
Recently, Zhang [14-15] considered the electric and color charges of quarks and antiquarks as two forms of imaginary energy in analogy with mass as a form of real energy and developed a classical unification theory that unifies all natural fundamental interactions with four natural fundamental elements, which are radiation, mass, electric charge, and color charge.
Larger groupings of quarks and antiquarks may have existed in the early universe and may persist today in extremely dense stars, says theorist Marek Karliner of Tel Aviv University.
For this reason, antiquarks, whose monopole unit has the same sign as that of the baryonic core, are pushed out to the baryonic external region and are enclosed inside a larger volume.
In addition, we introduce a three-dimensional energy space to describe all types of matter or particles including quarks and antiquarks.
the within-nucleon transition of a d-quark to a uquark, or the reverse, is associated with the formation of an antiquark, without the requirement of GeV energies necessary to break apart the nucleus.
In this formulation, quarks and antiquarks sit at points in a finite, four-dimensional lattice, and gluons correspond to the links between these points.
Also, we can define the strange antimatter as formed by a large number of antiquarks bound together with an antielectron around them.
Created as pairs of top quarks and antiquarks in collisions between protons and antiprotons moving at nearly the speed of light, these massive particles disintegrate almost immediately in ways that create a shower of other particles that can then be detected.
Antiquarks are characterized by an opposite electric charge so that the geometrical locus loop of the [bar.
It interacts with other quarks and antiquarks created out of the vacuum as it separates from what's left of the proton.
Detailed matrix operations confirm that hadrons with quark-antiquark pairs, three quarks, or three antiquarks, are colorless combinations.
