Ozi suppression
WebWhat is the precise statement of the OZI Rule? I've heard that a diagram is OZI suppressed if it can be "cut in two by cutting only gluon lines", but I don't really understand. For … WebSep 24, 1984 · A key ingredient in this analysis was the elimination of strange quark suppression factors by analyzing the OZI violation in the two processses y ~ K+K-pand …

WebMay 9, 2000 · Experiment is currently unable to identify these mesons, but we report here on a lattice QCD calculation which confirms that the OZI rule arises from QCD in the vector … Webexperiments very selectively completely broke down the OZI suppression by 3 phi phi resonances with IG JPC = 0+ 2++ in the observed mass region 2.038 to 2.600 GeV. The only viable proposed explanation has been that the IG JPC = 0+ 2++ Glueball expected in this mass region caused the hard glue in the disconnection
WebThe transition (la) has the typical OZI suppression factor for all strong * decays. The transition (lb) has the OZI violation In a state with the quantum numbers of the final state after the photon has carried away its angular momentum, parity and odd charge conjugation. This diagram has been invoked to explain the observed radiative decays The OZI suppressed processes have a higher ratio of vertices (which contribute factors of 1⁄Nc) to independent fermion loops (which contribute factors of Nc) when compared to the non-suppressed processes, and so these processes are much less common. See more The OZI rule is a consequence of quantum chromodynamics (QCD) that explains why certain decay modes appear less frequently than otherwise might be expected.

WebMar 11, 2024 · $\begingroup$ There is no shortcut steering you to the OZI rule without the benefit of Feynman (or quark and gluon) diagrams. It is basically a property of gluon … WebDec 19, 1985 · The observation of three resonances (in the reaction π-p → φφn) which break down the OZI suppression was attributed to the production of these states by glueball(s). Alternate explanations in terms of otherwise explaining the OZI suppression breakdown or finding other kinematic mechanisms to explain the BNL/CCNY data are …
WebSep 27, 1976 · This simple rule relates the suppression factor of an OZI forbidden vertex to a ratio between two OZI allowed amplitudes. Physically it means that, although initially only a kaon pair was emitted, the final state interaction between the kaons is so strong that it determines which particles eventually emerge.

Annihilation through a single gluon can't happen because the gluon has a colour+anticolour charge, whereas the initial meson is colourless.
