QCD Analysis of the Diffractive Measurements at HERA and Tevatron
L. Schoeffel
In the following, we present a QCD analysis of CDF data on single diffractive 
events and we extract the gluon fraction in the Pomeron from this study. 
Then, we combine both HERA and Tevatron results on diffraction in a same 
QCD framework to search for common parton distributions. As the dijet mass 
fraction, measured at CDF with a double diffractive exchange sample of events, 
is very sensitive to the gluon density in the Pomeron, we present some 
comparisons of this dijet mass fraction with gluon densities extracted from 
HERA or CDF single diffractive data.
