Proton structure function at small Q2
A Donnachie, P V Landshoff
Abstract
A fit is made to the data for the proton structure function up to Q2=10 GeV2, including the real gamma p total cross-section. It is economical and simple, and its form is motivated by physical principles. It is extrapolated down to very small values of x. Data for the ratio (nu W2n/nu W2p) are also fitted. A FORTRAN program for the fit to (nu W2p) is available by email on request Figure 5 from the original version has been deleted.
