Meson production in high-energy electron-nucleus scattering

Evidence of Coherent K^{+} Meson Production in Neutrino-Nucleus Scattering.

Neutrino-induced charged-current coherent kaon production ν_{μ}A→μ^{-}K^{+}A is a rare, inelastic electroweak process that brings a K^{+} on shell and leaves the target nucleus intact in its ground state. This process is significantly lower in rate than the neutrino-induced charged-current coherent pion production because of Cabibbo suppression and a kinematic suppression due to the larger kaon...

High Energy Photo - Meson Production from Hydrcx

High-energy pion-nucleus elastic scattering.

We investigate theoretical approaches to pion–nucleus elastic scattering at high energies (300 ≤ Tπ ≤ 1 GeV). A “model–exact” calculation of the lowest–order microscopic optical model, carried out in momentum space and including the full Fermi averaging integration, a realistic off–shell pion–nucleon scattering amplitude and fully covariant kinematics, is used to calibrate a much simpler theory...

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 ...

Elastic Electron - Deuteron Scattering at High Energy

Relativistic formulae for the deuteron electromagnetic form factors are calculated in the impulse approximation retaining terms to all orders in Q2/M2 z wc>2. The formulae are given as double integrals over the deuteron wave functions in momentum space, and hence can be evaluated for any deuteron model. We evaluate these formulae numerically for 9 different deuteron models: Reid soft core, two ...
