Meson Resonance Production in Two-photon Processes
states are directly related to short-distance structure at their inside. It will give us an answer whether the meson is normal q q meson or an exotic one. Spin-parity, J P , of the mesons can be determined by investigating the angular distribution of the decay products in cooperation with limited degree of freedom in the initial state composed of two real photons. The study for the decay modes ...
متن کاملPhoton + Hadron Production in High Energy Deuteron (Proton)-Nucleus Collisions
We apply the Color Glass Condensate formalism to photon + hadron production cross section in high energy deuteron (proton)-gold collisions at RHIC. We investigate the dependence of the production cross section on the angle between the produced hadron and photon for various rapidities and transverse momenta. It is shown that the angular correlation between the produced hadron and photon is a sen...
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 کاملMeson Retardation in Deuteron Photodisintegration Above
Photodisintegration of the deuteron above π-threshold is studied in a coupled channel approach including N ∆-and πd-channels with pion retardation in potentials and exchange currents. A much improved description of total and differential cross sections in the energy region between π-threshold and 400-450 MeV is achieved.
متن کاملVector Meson Pair Production in Two - Photon Collisions near Threshold
The cross sections for several γγ → V V processes exhibit strong enhancements near threshold, where V denotes a vector meson. The pattern of these enhancements is not well understood; for example, γγ → ρρ shows an appreciable peak, while γγ → ρρ does not. Some possible mechanisms for this behavior are discussed. Tests are proposed involving production of systems containing heavier quarks, e.g.,...
