Multiple parton scattering and induced parton energy loss is studied in deeply inelastic scattering (DIS) off nuclei. The effect of multiple scattering of a highly off-shell quark and the induced parton energy loss is expressed in terms of the modification to the quark fragmentation functions. We derive such modified...

We have searched for high Pt (>40 GeV/c) jet events in ppbar collisions at the Fermilab TEVATRON (S**1/2 = 1800 GeV/c2) which have large pseudo-rapidity differences between the jets and are consistent with zero particle production from the underlying event. Preliminary analysis indicates that a significant fraction of ...
