STUDY ON THE POMERON STRUCTURE-FUNCTION

A study about the Pomeron structure function based on diffractive deep inelastic scattering data measured at the DESY HERA experiments is pe rformed. In this study it is assumed that the diffractive structure fu nction is given by the product of the Pomeron flux factor and the Pome ron structure function. In order to obtain the Pomeron structure funct ion, two different forms of the Pomeron flux factor are employed, one that is usually obtained within the Regge pole phenomenology and anoth er which comes from the renormalization of the standard Regge flux fac tor. It is shown that these two schemes of analysis lead to very diffe rent conclusions about the Pomeron constitution in terms of quarks and gluons. [S0556-2821(98)04001-6].
