The reaction πN → ωN revisited : the ω − N scattering length
We reinvestigate the experimental data on ω–meson production in pion-nucleon collisions [1, 2, 3] based on both an analytical approach and a Monte Carlo simulation. Our analysis allows us to study the kinematical peculiarities of the π − p→ωn reaction at energies close to threshold. Based on the hypothesis, that the formalism derived in ref. [1] was applied improperly, the unusually strong ener...

We reanalyze the experimental data on ω–meson production in pion-nucleon collisions [1, 2, 3] based on both an analytical approach and a Monte Carlo simulation. Our analysis allows us to correct the data for the π − p→ωn reaction at energies close to threshold. The unusually strong energy dependence originally claimed for the near–threshold cross section is identified as a purely kinematical ef...

متن کاملNear - threshold ω - meson production in proton - proton collisions ∗ : With or without resonance excitations ?
We present results for the pp → ppω reaction studied by considering two different scenarios: with and without the inclusion of nucleon resonance excitations. The recently measured angular distribution by the COSY-TOF Collaboration at an excess energy of Q = 173 MeV and the energy dependence of the total cross section data for π−p → ωn are used to calibrate the model parameters. The inclusion of...
