Three channel model of meson-meson scattering and scalar meson spectroscopy
New solutions on the scalar – isoscalar ππ phase shifts are analysed together with previous KK results using a separable potential model of three coupled channels (ππ , KK and an effective 2π2π system). Model parameters are fitted to two sets of solutions obtained in a recent analysis of the CERN-Cracow-Munich measurements of the πp↑ → π +π−n reaction on a polarized target. A relatively narrow ...
متن کاملCharm Meson Production from Meson-nucleon Scattering
Because of their large masses, one expects charm mesons to be mostly produced in the initial preequilibrium stage of relativistic heavy ion collisions. They have thus been suggested as possible probes of the initial dynamics in these collisions. Previous studies have been concentrated on the production of charm quarks from the preequilibrium partonic matter [1]. For charm meson production from ...
متن کاملMeson-nucleon Elastic Scattering and Photo-meson Production via the U-channel’
An explanation of the available pion-nucleon and photo-meson production data in the backward direction is proposed using Baryon trajectories. Special emphasis is given to the constraints, the unequal mass kinematics and their implications. I// (Submitted to Phys. Rev. Letters) t Work supported by the U. S.

متن کاملPeculiarities in multichannel interaction amplitudes for meson-meson scattering and scalar meson spectroscopy
Interactions in coupled channels ππ, KK̄ and an effective 2π2π in scalar-isoscalar wave have been analysed. Influence of interchannel couplings on analytical structure of multichannel interaction amplitudes has been studied. Interplay of S-matrix zeroes and poles and their relation with parameters of scalar resonances has been investigated. PACS numbers: 11.80.Gw, 13.60.Le, 13.75.Lb, 14.40.Cs St...
متن کاملCharm meson scattering cross sections by pion and rho meson
Using the local flavor SU(4) gauge invariance in the limit of vanishing vector meson masses, we extend our previous study of charm meson scattering cross sections by pion and rho meson, which is based only on the pseudoscalarpseudoscalar-vector meson couplings, to include also contributions from the couplings among three vector mesons and among four particles. We find that diagrams with light m...
