This book was released on 2007 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors present results of a search at CDF in 929 ± 56 pb−1 of p{bar p} collisions at 1.96 TeV for the anomalous production of events containing a high-transverse momentum charged lepton (l, either e or?) and photon , accompanied by missing transverse energy (E{sub T}), and/or additional leptons and photons, and jets (X). They use the same selection criteria as in a previous CDF Run I search, but with an order-magnitude larger data set, a higher p{bar p} collisions energy, and the CDF II detector. They find 163 l?E{sub T} + X events, compared to an expectation of 150.6 ± 13.0 events. They observe 74 ll? + X events, compared to an expectation of 65.1 ± 7.7 events. They find no events similar to the Run II ee??E{sub T} event.
