from January 19, 2006 mentions studies made by Dzero collaboration of the products of extremely hard collisions between protons and their antimatter counterparts, antiprotons, at the Tevatron Collider. A measurement of the production rate (or cross section) of a Z boson with jets over a range of jet multiplicities is shown. The article contains a picture of UIC analysis team participating in this study. Shown are Marc Buehler (now with University of Virginia), Alan Stone, Professor Nikos Varelas
