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 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 کاملPartially-Quenched Nucleon-Nucleon Scattering
Nucleon-nucleon scattering is studied to next-to-leading order in a partially-quenched extension of an effective field theory used to describe multinucleon systems in QCD. The partially-quenched nucleon-nucleon amplitudes will play an important role in relating lattice simulations of the two-nucleon sector to nature.
متن کاملReduction of neutrino - nucleon scattering rate by nucleon - nucleon collisions
The collapse-driven supernova is supposed to be an outcome of gravitational collapse of a massive star ∼ 8M at the end of its evolution. Although more than 60 years have passed since the original idea by Baade and Zwicky [1,2], and the detection of neutrinos from SN1987A [3,4] confirmed that our scenario is correct on the whole, we have not yet figured out how this phenomenon occurs. These days...
