Photon Total Cross - sections
We discuss present predictions for the total γγ and γp cross-sections, highlighting why predictions differ. We present results from the Eikonal Minijet Model and improved predictions based on soft gluon resummation.
متن کاملModels for Photon-photon Total Cross-Sections
We present here a brief overview of recent models describing the photon-photon cross-section into hadrons. We shall show in detail results from the eikonal minijet model, with and without soft gluon summation.
متن کاملPHOTON-NUCLEUS TOTAL CROSS SECTIONSt
Quantitative predictions for the energy and A dependence of the nuclear photoabsorption cross section and inelastic electron-nucleus scattering are given. In general each nucleon does not contribute equally to the total photon-nucleus cross section when coherent contributions of photoproduced hadrons are taken into account. At low energies (E Y N 1 BeV) the cross sections are proportional to nu...
متن کاملSimple function forms and nucleon-nucleus total cross sections
School of Physics, The University of Melbourne, Victoria 3010, Australia (Dated: April 7, 2004) Abstract Total cross sections for neutron scattering with energies between 10 and 600 MeV and from nine nuclei spanning the mass range from 6Li to 238U have been analyzed using a simple function of three parameters. The values of those parameters with which neutron total cross-section data are replic...
متن کاملPredicting total reaction cross sections for nucleon-nucleus scattering.
Nucleon total reaction and neutron total cross sections to 300 MeV for 12C and 208Pb, and for 65 MeV scattering spanning the mass range, are predicted using coordinate space optical potentials formed by full folding of effective nucleon-nucleon interactions with realistic nuclear ground state densities. Good to excellent agreement is found with existing data.
