    The bottom quark or b quark, also known as the beauty quark, is a third-generation heavy quark with a charge of −1/3 e. All quarks are described in a similar way by electroweak and quantum chromodynamics, but the bottom quark has exceptionally low rates of transition to lower-mass quarks. The

    A quark is a type of elementary particle and a fundamental constituent of matter. Quarks combine to form composite particles called hadrons, the most stable of which are protons and neutrons, the components of atomic nuclei. All commonly observable matter is composed of up quarks, down quarks and electrons. Owing to a phenomenon known as color confinement, quarks are never found in isolation; they can be found only within hadrons, which include baryons (such as proton…

    What is a bottom quark?
    Jump to navigation Jump to search. The bottom quark or b quark, also known as the beauty quark, is a third-generation quark with a charge of −13 e. All quarks are described in a similar way by electroweak and quantum chromodynamics, but the bottom quark has exceptionally low rates of transition to lower-mass quarks.

    What is a single top quark?
    Single top quarks. This can happen in several ways (called channels): either an intermediate W-boson decays into a top and antibottom quark ("s-channel") or a bottom quark (probably created in a pair through the decay of a gluon) transforms to a top quark by exchanging a W-boson with an up or down quark ("t-channel").

    Why is the top quark so massive?
    The top quark, sometimes also referred to as the truth quark, (symbol: t) is the most massive of all observed elementary particles. It derives its mass from its coupling to the Higgs Boson. This coupling

    Is it possible to combine a bottom antiquark and a top quark?
    The combination of a bottom antiquark and a top quark is not thought to be possible because of the top quark's short lifetime. The combination of a bottom antiquark and a bottom quark is not a B meson, but rather bottomonium which is something else entirely.

    Bottom quark From Simple English Wikipedia, the free encyclopedia Bottom quarks or beauty quarks are the second most massive of the elementary particles ( particles that are so small that they can not be divided any more). All quarks are elementary particles. Bottom quarks have a charge of -1/3, similar to down quarks.

    It was in fact not long until a fifth quark, the bottom, was discovered by the E288 experiment team, led by Leon Lederman at Fermilab in 1977. This strongly suggested that there must also be a sixth quark, the top, to complete the pair.

    Nucleons are the fermionic constituents of normal atomic nuclei: Protons, composed of two up and one down quark (uud) Neutrons, composed of two down and one up quark (ddu) Hyperons, such as the Λ, Σ, Ξ, and Ω particles, which contain one or more strange quarks, are short-lived and heavier than nucleons.

  10. https://en.wikipedia.org/wiki/B_meson

    From Wikipedia, the free encyclopedia In particle physics, B mesons are mesons composed of a bottom antiquark and either an up ( B+ ), down ( B0 ), strange ( B0 s) or charm quark ( B+ c ). The combination of a bottom antiquark and a top quark is not thought to be possible because of the top quark's short lifetime.

  11. https://en.wikipedia.org/wiki/Charm_quark

    The charm quark, charmed quark or c quark (from its symbol, c) is the third most massive of all quarks, a type of elementary particle.Charm quarks are found in hadrons, which are subatomic particles made of quarks. Examples of hadrons containing charm quarks include the J/ψ meson ( J/ψ), D mesons ( D), charmed Sigma baryons ( Σ c), and other charmed particles.
