PT Journal AU CDF Collaboration (Aaltonen, Tea Cabrera, S TI Search for anomalous production of events with two photons and additional energetic objects at CDF SO Physical Review D JI Phys. Rev. D PY 2010 BP 052005 EP 27pp VL 82 IS 5 DI 10.1103/PhysRevD.82.052005 LA English AB We present results of a search for anomalous production of two photons together with an electron, muon, tau lepton, missing transverse energy, or jets using p (p) over bar collision data from 1.1-2.0 fb(-1) of integrated luminosity collected by the Collider Detector at Fermilab (CDF). The event yields and kinematic distributions are examined for signs of new physics without favoring a specific model of new physics. The results are consistent with the standard model expectations. The search employs several new analysis ER
