Abstract
This Letter presents a search for exclusive boson production in proton-antiproton collisions at , using the CDF II detector. No exclusive candidates are observed and the first upper limit on the exclusive cross section in hadron collisions is found to be at 95% confidence level. In addition, eight candidate exclusive dilepton events from the process are observed, and a measurement of the cross section for and is found to be , which is consistent with the standard model prediction.
