Let us assume that there is a characteristic radius (residual radius) [r.sub.0] of the quark and antiquark system (which is the smallest distance between the two quarks where they cannot collide with each other).

The high energy at the time and the creation and destruction of a large number of quarks and antiquarks would also create a variety of flux tubes, some of which could be knots.

Each quark has an anti-matter equivalent known as antiquark. Both protons and neutrons - contained within the nucleus of an atom - are made up of three quarks bound together.

Each particle also has an antiparticle, such as an antiquark. Atomic nuclei are made of protons and neutrons, which in turn are made of quarks.

A quark (antiquark) has a baryon number 1/3 (-1/3), while SM lepton has 0.

In meson for example (a simpler case) the quark and the antiquark must undergo rapid interchange of identity into each other (through exchange of force particles) to remain in a stable form.
