On the current status of OZI violation in πN and pp reactions ⋆
نویسندگان
چکیده
The available data on ω and φ production from πN and pp collisions are reanalyzed with respect to an OZI rule violation on the basis of transition matrix elements. The data are found to be compatible with a constant ratio R up to excess energies ǫ≈300 MeV, however, the ratio R deviates substantially from the SU(3) prediction based on the present knowledge of the φ − ω mixing angle.

v 1 2 6 O ct 1 99 8 The Reaction pp → ppφ and the Validity of the OZI Rule ∗
The reaction pp → ppφ is investigated within a relativistic mesonexchange model of hadronic interactions. The possibility of extracting the NNφ coupling constant from a study of this process is explored. A combined analysis of ω− and φ-meson production in proton-proton collisions utilizing recent data on these reactions is carried out and yields values for gNNφ that are compatible with the OZI ...
متن کاملThe Conditions of the Violations of Le Chatlier’s Principle in Gas Reactions at Constant T and P
Le Chatelier's principle is used as a very simple way to predict the effect of a change in conditions on a chemical equilibrium. . However, several studies have reported the violation of this principle, still there is no reported simple mathematical equation to express the exact condition of violation in the gas phase reactions. In this article, we derived a simple equation for the violation of...

Results of a combined analysis are presented for the production of ω and φ mesons in πN reactions in the near-threshold region using throughoutly a conventional ”non-strange” dynamics based on such processes which are allowed by the non-ideal ω − φ mixing. We show that strong interferences of the t (meson exchange) and s and u (nucleon and nucleon resonance) channels differ significantly in ω a...

We analyze near-threshold cross section data for the reaction pp→ppφ published by the DISTO collaboration and recent, still preliminary results presented by the ANKE Collaboration. We formulate a procedure to evaluate the OZI ratio at low energies by taking into account corrections from the kinematics and the final-state interaction. Combining the new data with the few measurements available at...

We analyze the production of φ mesons in πN and N N reactions in the near-threshold region, using throughout the conventional " non-strange " dynamics based on such processes which are allowed by the non-ideal ω − φ mixing. We show that the occurrence of the direct φN N interaction may show up in different unpolarized and polarization observables in πN → N φ reactions. We find a strong non-triv...
