Charm 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 کاملPion-Nucleon Scattering in Kadyshevsky Formalism: I Meson Exchange Sector
In a series of two papers we present the theoretical results of πN/meson-baryon scattering in the Kadyshevsky formalism. In this paper the results are given for meson exchange diagrams. On the formal side we show, by means of an example, how general couplings, i.e. couplings containing multiple derivatives and/or higher spin fields, should be treated. We do this by introducing and applying the ...
متن کاملNucleon Resonances in Meson Nucleon Scattering with Strangeness Production
An effective Lagrangian model in a coupled channels framework is applied to extract nucleon resonance parameters. In the K-matrix approximation, we simultaneously analyze all the available data for the transitions from πN to five possible meson-baryon final states, πN, ππN, ηN,KΛ, and KΣ, in the energy range from πN threshold up to √ s = 2 GeV. In this work, we focus our efforts on the KΣ chann...
متن کاملA unitary model for meson-nucleon scattering
In an effective Lagrangian model employing the K-matrix approximation we extract nucleon resonance parameters. To this end we analyze simultaneously all available data for reactions involving the final states πN , ππN , ηN and KΛ in the energy range mN + mπ ≤ √ s ≤ 1.9 GeV. The background contributions are generated consistently from the relevant Feynman amplitudes, thus significantly reducing ...
متن کاملFrom Meson-nucleon Scattering to Vector Mesons in Nuclear Matter
We employ meson-nucleon scattering data to deduce the properties of the low-mass vector mesons in nuclear matter, and present results for the ρ and ω in-medium spectral functions. The corresponding thermal emission rate for lepton pairs is also discussed.
