The ALLM parameterization of #sigma#_t_o_t(#gamma#"*p). An update

Abstract

The ALLM parameterization of #sigma#_t_o_t(#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 ranges studied so far (3 x 10"-"6<x<0.85, 0#<=#Q"2<5000 GeV"2).
