The e + e − → P 1 P 2 γ processes close to the Φ peak : toward a model - independent analysis

چکیده
We discuss the general decomposition and possible general parameterizations of the processes e+e− → γ → P1P2γ, where P1P2 = π0π0, π0η, or π+π−, for √ s ≈ MΦ. Particular attention is devoted to the amplitude where the two pseudoscalar mesons are in a JCP = 0++ state, where we propose a general parameterization which should help to shed light on the nature of light scalar mesons.

Measuring the finite width and unitarity corrections to the φω mixing amplitude. Abstract It is shown that the phase of φω interference in the reaction e + e − → π + π − π 0 at energies close to the φ(1020) peak can be calculated in a way that is practically independent of the model of φω mixing. The magnitude of the presently measured interference phase, still of poor accuracy, is in agreement...
متن کاملAzimuthal Dependence in Diffractive Processes
Azimuthal distributions in high-energy processes give information about the helicity structure of diffractive reactions. I discuss predictions of several dynamical mechanisms in this context, both for electron-proton and for hadron-hadron collisions. 1 Azimuthal distributions in ep diffraction In this talk I give several examples of what azimuthal distributions can tell us about diffractive int...
