Murray Gell-Mann and Geroge Zweig, working independently, first propossed the quark theory in 1964. George Zwieg later won the Nobel Prize for advancement in physics with his discovery of the 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.
The two fundamental particles based on quark theory are quarks, which are the building blocks of matter, and leptons, which include electrons and neutrinos. Quarks are bound together by the strong nuclear force to form protons and neutrons, while leptons do not participate in the strong force.
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 CopyDesk was created in 1991.
Whoever first read it after it was formulated.
the original big bang theory ended in a big crunch. the modern dark energy theory says it will keep expanding ever faster until it is ripped apart and no quark will be able to detect any other quark, and it will still keep expanding faster and faster.

The term "quark" comes from the book "Finnegans Wake" by James Joyce. Physicist Murray Gell-Mann chose this whimsical term to name the elementary particles he proposed as building blocks of protons and neutrons.
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.

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.
