An anti-up quark is an antiquark which corresponds to the up 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.
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.
Quark CopyDesk was created in 1991.
Quark Pharmaceuticals was created in 1993.
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.
It depends on the exact antiparticle you are talking about. When a particle has an electric charge, its antiparticle would have an equal, but opposite charge. For example, protons have a charge of +1, while antiprotons have a charge of -1. This applies to all electrically charged particles, including quarks (particles that make up hadrons) When a particle is a hadron (composite particle), then usually the quarks inside them are antiquarks. For example, the quark structure of a neutron is udd (up up down) while the quark structure of an antineutron is antiup, antidown, antidown. The charges cancel each other out, and antineutrons are left with no charge, just like neutrons. If the particle had charge, then the combination of charges of its antiparticle's quarks would be equal, but of opposite. In addition, some other properties are also the same, but opposite, Some particles (eg. photons, Z bosons) are their own antiparticles.

The final quark, the Top Quark, was discovered in 1995 at FermiLab.
Quark Pharmaceuticals's population is 2,006.
The up quark, the down quark, and the electron. Two up quarks and a down quark form a proton, and two down quarks and an up quark form a neutron.
