Experimental rates of W and dijets diffractively produced at the Tevatron Collider have recently become available. We use parametrizations of the pomeron structure function obtained from HERA data by two different schemes to compare theoretical expectations with the measured rates.

A review is presented of numerous recent results, particularly those submitted to the EPSHEP99 conference: very high Q ep interactions and direct tests of the Standard Model, new measurements of the structure of the proton (including high x parton distributions and tests of QCD involving the gluon distribution), low x physics (tests of the BFKL evolution), diffraction in DIS at HERA, hard diffr...

We study the single production of first generation leptoquarks in association with a e at the Fermilab Tevatron. We focus our attention on final states exhibiting a e+e− pair and jets, and perform a detailed analyses of signal and backgrounds. The single leptoquark production cross section depends on the leptoquark Yukawa coupling to lepton-quark pairs and we show that the study of this mode ca...
