Abstract

The first measurements of the diffractive structure function F2D(3)F_2^{D(3)} at HERA are discussed. A factorisable interpretation in which a partonic structure is assigned to the pomeron is investigated through QCD analyses in which both the quark and gluon densities are permitted to vary freely. A method of measuring the longitudinal structure function of the pomeron without changing the epep centre of mass energy is presented. The possibility that the pomeron structure may receive a large contribution from gluons, relative to quarks, at high β\beta is highlighted, and the experimental signatures which may support such a structure are reviewed.
