Inclusive electroproduction from protons and deuterons

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...

Electroproduction of Charmonia off Protons and Nuclei

Elastic virtual photoproduction of charmonia on nucleons is calculated in a parameter free way with the light-cone dipole formalism and the same input: factorization in impact parameters, light-cone wave functions for the photons and the charmonia, and the universal phenomenological dipole cross section which is fitted to other data. The charmonium wave functions are calculated with four known ...

Of Inclusive Electroproduction of Hadrons ”

Mueller's Regge analysis is combined with the generalized scaling laws of the parton model to determine the Q2-dependence of inclusive electroproduction of hadrons.
