Meson Production Near Threshold in Nucleon-Nucleon Collisions
The PROMICE/WASA collaboration has studied and meson production in nucleon-nucleon collisions near threshold using the CELSIUS ring at the The Svedberg Laboratory, Uppsala. Some of the reaction channels are measured for the rst time in any detail. The results are presented together with an outlook.
متن کاملMeson production in nucleon–nucleon collisions close to the threshold
The last decade has witnessed great experimental progress that has led to measurements of near threshold cross sections—polarized as well as unpolarized—of high accuracy for various inelastic nucleon–nucleon collision channels. These data, naturally, pose challenges to theorists to develop methods by which they can be understood and explained in commensurate detail. In this work we review the s...
متن کاملCharm 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 کاملFSI Corrections For Near Threshold Meson Production In Nucleon-Nucleon Collisions
A procedure is proposed which accounts for final state interaction corrections for near threshold meson production in nucleon-nucleon scattering. In analogy with the Watson-Migdal approximation, it is shown that in the limit of extremely strong final state effects, the amplitude factorizes into a primary production amplitude and an elastic scattering amplitude describing a 3 → 3 transition. Thi...
متن کاملProbing the Nucleon’s Transversity Via Two-Meson Production in Polarized Nucleon-Nucleon Collisions∗
We explore the possibility of probing the nucleon’s transversity distribution δq(x) through the final state interaction between two mesons (ππ, πK, or KK) produced in transversely polarized nucleon-nucleon collisions. We present a single spin asymmetry and estimate its magnitude under some assumptions for the transversity distribution function and the unknown interference fragmentation function...
