Vector meson. The vector mesons consisting of light quarks form a nonet. In high energy physics, a vector meson is a meson with total spin 1 and odd parity (usually noted as JP = 1−). Vector mesons have been seen in experiments since the 1960s, and are well known for their spectroscopic pattern of masses. [1]
Mesons named with the letter "f" are scalar mesons (as opposed to a pseudo-scalar meson), and mesons named with the letter "a" are axial-vector mesons (as opposed to an ordinary vector meson) a.k.a. an isoscalar vector meson, while the letters "b" and "h" refer to axial-vector mesons with positive parity, negative C-parity, and quantum numbers I G of 1 + and 0 − respectively.
Phi meson. meson is a vector meson formed of a strange quark and a strange antiquark. It was the. that led to the discovery of the OZI rule. It has a mass of 1 019.461 ± 0.020 MeV/ c2 and a mean lifetime of 1.55±0.01 × 10−22s.
0 ħ, 1 ħ. In particle physics, a meson (/ ˈmiːzɒn, ˈmɛzɒn /) is a type of hadronic subatomic particle composed of an equal number of quarks and antiquarks, usually one of each, bound together by the strong interaction. Because mesons are composed of quark subparticles, they have a meaningful physical size, a diameter of roughly one ...
The 1 ++ multiplet of light mesons may show similar behavior to that of other vector mesons, in that the mixing of light quarks with strange quarks appears to be small for this quantum number. The 1 +− multiplet, on the other hand, may be affected by other factors that generally reduce meson masses.
Eta and eta prime mesons. ) are isosinglet mesons made of a mixture of up, down and strange quarks and their antiquarks. The charmed eta meson (. defined, but are made of charm quarks and bottom quarks respectively. The top quark is too heavy to form a similar meson, due to its very fast decay.
In high-energy physics, a pseudoscalar meson is a meson with total spin 0 and odd parity (usually notated as JP = 0− ).[1][a] Pseudoscalar mesons are commonly seen in proton -proton scattering and proton-antiproton annihilation, and include the pion (π), kaon (K), eta (η), and eta prime (η ′) particles, whose masses are known with great ...
The neutral B mesons, B0. and. B0. s, spontaneously transform into their own antiparticles and back. This phenomenon is called flavor oscillation. The existence of neutral B meson oscillations is a fundamental prediction of the Standard Model of particle physics. It has been measured in the.
