Recent results on diffractive dijet and vector boson production and exclusive dijet production from the Collider Detector at Fermilab (CDF) experiment are presented.

We present the first observation and cross section measurement of exclusive photon pair production in proton-antiproton collisions at √ s = 1.96 TeV taken by the Run II Collider Detector at Fer-milab. We select events with two electromagnetic showers, each with transverse energy E T > 2.5 GeV and pseudorapidity |η| < 1.0, with no other particles detected in −7.4 < η < +7.4. The two showers have...
