چکیده
Combined analysis of η and η ′ hadro-and photo-production off nucleons * The production of η and η ′ mesons in photon-and hadron-induced reactions are studied in a combined analysis based on an effective Lagrangian approach in order to learn about the relevant production mechanisms and the possible role of nucleon resonances in these reactions.

The photo-and electroproduction of the η, η ′ mesons on nucleons are investigated within a relativistic chiral unitary approach based on coupled channels. The s-wave potentials for electroproduction and meson-baryon scattering are derived from a chiral effective Lagrangian which includes the η ′ as an explicit degree of freedom and incorporates important features of the underlying QCD Lagrangia...
متن کاملPhotoproduction of η ′ - mesons off the deuteron
Quasi-free photoproduction of η′-mesons off nucleons bound in the deuteron has been measured with the combined Crystal Barrel TAPS detector. The experiment was done at a tagged photon beam of the ELSA electron accelerator in Bonn for incident photon energies from the production threshold up to 2.5GeV. The η′-mesons have been detected in coincidence with recoil protons and recoil neutrons. The q...
متن کاملProduction and interaction of the η meson with nucleons and nuclei
We report on the status of the search for η-mesic nuclei and the studies of the interaction of the η meson with nucleons. Recently we have completed the analysis of the new WASA-at-COSY data on the production of the η meson with polarized proton beam. New results on the analyzing power for the ~pp → ppη reaction with more than an order of magnitude improved precision shed a new light on the pro...
متن کاملHigher Orders in the Colour - Octet Model of J / ψ Production
We study the hadro-and photo-production of ¯ cc and ¯ bb mesons at low transverse momentum to high orders in the relative velocity of the pair, v, in non-relativistic QCD. We evaluate cross sections to order v 7 for η c , sufficient for studies of photo-production in the almost-elastic region. For all other charmonium states we find the cross section to order v 9 , sufficient for studies of the...
متن کاملη-mesic nuclei in relativistic mean-field theory
With the η-nucleon (ηN) interaction Lagrangian deduced from chiral perturbation theory, we study the possible η-mesic nuclei in the framework of relativistic mean-field theory. The η single-particle energies are sensitive to the ηN scattering length, and increase monotonically with the nucleon number A. If the scattering length is in the range of a = 0.75 ∼ 1.05 fm and the imaginary potential V...
