The six quark flavors are up, down, strange, charmed, bottom, and top. The top quark was the last to be created in an accelerator since its mass was so great; after a nearly 20 year search it finally was announced by Fermilab.
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.
Quark
A quark is the smallest known particle, which makes up protons and neutrons found in the nucleus of atoms. This means that quarks are smaller than protons, neutrons, atoms, and molecules.
Actually 'an' up quark.The weak nuclear force permits an interaction between an up quark and an electron that converts the up quark to a down quark and the electron ceases to exist, also an interaction between a down quark and a positron that converts the down quark to an up quark and the positron ceases to exist. There are also weak nuclear force interactions that change quark types by emitting electrons or positrons. Both the absorption and emission interactions described above are referred to as Beta Decay Processes. All Beta Decay Processes also involve emission of an electron neutrino or an electron antineutrino (the lightest known particle having a nonzero mass and a particle that has almost no interaction at all with other matter).
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.
The sixth quark is known as the top quark. It is the most massive of all quarks and was discovered in 1995 at the Fermi National Accelerator Laboratory. The top quark plays a crucial role in understanding the Standard Model of particle physics.
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.
The most massive of all known elementary particles is the top quark.
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.
