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.
So, physicists must turn to theory to distinguish those features due exclusively to the decay of the b quark from the elaborate dance of quarks, antiquarks, and gluons inside a decaying B meson.
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.
Figure 1 is a schematic diagram that shows formations of four generations of leptons from annihilations of up and down quarks and antiquarks with one excited quantum state for each of them.
The x-width of antiquarks is much smaller than that of quarks.
For one thing, it could end what had been a puzzling absence of evidence for particles with groupings containing more than three quarks or antiquarks, which theorists for decades have been expecting to show up in accelerators.
Quarks and their antiquarks are distributed in different phases by symmetrically with respect to the real-energy axis and separated by the plane of the real and electric imaginary energy axes.
One clue would be a sudden outpouring of thousands of hadrons, which are particles made up of quarks and antiquarks.
This is known as Yukawa coupling, and it is the Yukawa meson that carries the antiquark which couples to an up-quark of the proton.
Like other mesons, DsJ(2632) is thought to contain one quark--a strange quark--and one antiquark--a charm antiquark.
