Nothing, quarks are the sole matter of things, they are the base of things.
Quark is the smallest particle ever discovered.
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 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 anti-strange quark is an antiquark corresponding to the strange quark.
An anti-up quark is an antiquark which corresponds to the up quark.
An anti-beauty quark is an obsolete term for the anti-bottom quark.
Quark.
Relative means that it is compared to something. For example, the relative charge of a proton is +1 and it is relative to that proton. The relative charge of an electron is -1 relative to protons. That means it is exactly the same, but opposite. The relative charge of an up quark is +2/3, and that means that the charge of that quark is 2/3 of the charge of the proton. It depends what it is compared to.
A Quark, is the smallest.
The final quark, the Top Quark, was discovered in 1995 at FermiLab.

An antibottom quark is another name for the bottom antiquark, the antiparticle of the bottom quark.
Quark quark.
Quark Pharmaceuticals was created in 1993.
Quark - techfest - was created in 2006.
