The ALLM parameterization of sigma(tot)(gamma* p): An Update
Dec, 1997Citations per year
Abstract:
The ALLM parameterization of sigma_{tot}(gamma* p) has been updated by using all published F_2 data to determine its parameters. The fit yields a chi^2/ndf of 0.97 for the 1356 data points. The updated ALLM parameterization, ALLM97, gives a good description of all the available data in the whole x and Q^2 range studied so far (3\times10^{-6} < x < 0.85, 0 \le Q^2 < 5000 GeV^2).- electron p: deep inelastic scattering
- photon p: interaction
- total cross section: energy dependence
- dependence: momentum transfer
- total cross section: parametrization
- p: structure function
- numerical calculations: interpretation of experiments
