Current scientific theory places the production (creation) of naturally occurring quarks prior to the end of the inflationary period; later during the "hadron epoch" after the Big Bang when the universe had cooled sufficiently, the familiar baryons, composed of quarks, could form - such as neutrons and protons - and were able to coalesce from the quark-gluon plasma.
In the laboratory setting it is possible to create quarks in high energy collisions; the energy of the collision needs to be adequate to produce them - i.e., it would have to be at least equal to their mass-energy as described by the matter-energy equivalence equation (E=mc^2). The greater the mass, the more energy is required. Because it's not completely predictable, the production of a quark is somewhat random, other particles may be produced in any given collision, and it is more of a statistical phenomenon than a deterministic method.
That error bothered me quite often years ago while using Quark 4.0. One way to fix it is throw away the quark preferences file and restart, a longer fix, totally reinstall Quark.
Quark is the smallest particle ever discovered.
Quark types are referred to as "flavors". The quark flavors are called: Up (u), Down (d), Charm (c), Strange (s), Top (t) and Bottom (b).
A Meson is a subatomic particle that comprises of 1 quark and 1 anti-quark.
Fundamental particles include: 1. photon 2. electron 3. positron 4. proton 5. anti-proton 6. neutron 7. anti-neutron 8. neutrino 9. anti-neutrino 10. Higgs particle 11. muon 12. pion 13. top quark 14. bottom quark 15. up quark 16. down quark 17. strange quark 18. charm quark
An antibottom quark (or b-bar quark) is the antiparticle of a bottom quark. It has the same mass as a bottom quark but opposite electric charge and other quantum numbers. When a bottom quark meets an antibottom quark, they can annihilate each other and produce energy.
Quark.
Neutral pions are composed of a quark-antiquark pair, specifically an up quark and an anti-up quark or a down quark and an anti-down quark. They are the lightest mesons and are unstable, decaying rapidly into two photons.
An anti-down quark is the antimatter counterpart of a down quark, one of the elementary particles that make up protons and neutrons in the atomic nucleus. It has opposite electric charge to a down quark and can combine with other quarks to form antimatter particles.
Quark Pharmaceuticals was created in 1993.
Quark CopyDesk was created in 1991.

An anti-beauty quark, also known as a bottom antiquark, is the antiparticle counterpart of the beauty quark. It is a fundamental particle that has the opposite electric charge and other quantum numbers compared to the beauty quark. When a beauty quark and an anti-beauty quark pair up, they annihilate each other, releasing energy in the form of other particles.
Ans 1 Any with a combination of an up, charm, or top quark, and a combination of two down, strange, or bottom quarks. ([(+2)+(-1)+(-1)=(0)]). Ans 2 Two down quarks and an up quark. This combination is a neutron. A down quark has a charge of -1/3 and an up quark a charge of +2/3
Quark quark.
The final quark, the Top Quark, was discovered in 1995 at FermiLab.
