The φ - Meson Physics in the Chiral Model

+ → φ decays are studied using the method of phenomenological chiral Lagrangians. Calculated values for partial widths for these decay channels are compared with available experimental data. At present investigations of the ) 1020 ( φ - meson decays in experiments (1) and in the framework of theoretical models (2) are intensively carried out. It should be noted, that such decay channels of the φ - meson are not considered in chiral models and there are a few attempts (3) to calculate only some radiative decay channels of this meson. Studies of decay channels of this meson in chiral models are of interest because of the following reasons: First, the φ - meson mass is comparable to the chiral symmetry breaking scale of 1 GeV, the proposed decays into a rather heavy meson (theρ or ω of about 800 MeV) and a light meson (the π or K ) might be manageable along the lines of heavy- mass chiral perturbation theory (similarly to the heavy-baryon chiral perturbation theory of the pion-nucleon sector); Second, this meson (also another particles) are produced in colliders, for example, at the cooler synchrotron ring (COSY) at the Institut fuer Kernphysic at the Forschungzentrum Juelich in proton-proton collisions. And in this case the environment has a temperature not equal zero. Therefore, we need to take into account the influence of temperature factors of the environment to the decay
