Protons, Deuterons and Flow
Proton and deuteron mT spectra and rapidity densities at y = 1.9− 2.3 are presented for central SS, SPb and PbPb collisions. The inverse slopes increase with system size and mass. The radius parameter, RG, extracted from ratios of the spectra increases with system size. RG ∝ 1/ √ mT consistent with transverse flow and NA44’s HBT results. Experiment NA44 NA44 measures particle spectra and correl...
متن کاملGrazing Incidence Reflection and Scattering of MeV Protons
Treating protons as de Broglie waves shows that up to a few MeV energies protons experience total external reflection using the index of refraction concept for the target earlier applied to electrons. Angular scattering distributions can be explained by random surface scattering as known for X-rays. Applied to the Chandra and XMM-Newton X-ray telescopes the calculated reflection efficiencies ca...

متن کاملPhotoproduction of η-mesons off protons and deuterons
An effective field theory with hadrons and photons is constructed, where the hadronic parameters are determined by fitting elastic πN scattering data. The predicted pioninduced η-production on the nucleon agrees well with the data. The hadronic model is then used to describe the final-state interaction in photoinduced processes. We present a consistent description of pion photoproduction in the...
