Threshold meson production and cosmic ray transport
An interesting accident of nature is that the peak of the cosmic ray spectrum, for both protons and heavier nuclei, occurs near the pion production threshold. The Boltzmann transport equation contains a term which is the cosmic ray flux multiplied by the cross section. Therefore when considering pion and kaon production from proton-proton reactions, small cross sections at low energy can be as ...
متن کاملTHE SPINLESS SALPETER EQUATION AND MESON DYNAMICS
Applying the variational method, the spinless reduced Bethe-Salpeter (RBS) equation is solved for the mesonic systems, and the mass spectra are obtained. The method is applied to the Hamiltonian with the Gaussian and hydrogen-type trial wave functions, and different potential models are examined. The results for the different potentials are in challenge in light mesons, while they are consisten...
متن کاملNuclear medium effects on the K̄∗ meson
The K̄ meson in dense matter is analyzed by means of a unitary approach in coupled channels based on the local hidden gauge formalism. The K̄ selfenergy and the corresponding K̄ spectral function in the nuclear medium are obtained. We observe that the K̄ develops a width in matter up to five times bigger than in free space. We also estimate the transparency ratio of the γA → KKA reaction. This rati...
متن کاملMeson Production and Meson Properties at Finite Nuclear Density
The properties of π, η,K and K− mesons are studied in nuclear reactions from SIS to SPS energies within the covariant transport approach HSD in comparison to the experimental data. Whereas the pion, η and kaon abundancies and spectra indicate little or vanishing selfe-nergies for these mesons in the medium, antikaons (as well as antiprotons) are found to experience strong attractive potentials ...
متن کاملChiral Unitary approach to meson-meson and meson-baryon interactions and nuclear applications
We report on recent nonperturbative techniques that combine the information of chiral Lagrangians (with and without resonances) with unitarity in coupled channels and other requirements of the S-matrix theory of the strong interactions. As a result, the region of applicability of such techniques is much larger than the one of Chiral Perturbation Theory allowing one to study also resonance physi...
