 Title: Search for Anomalous Production of Events with Two Photons and Additional Energetic Objects at CDF Author: Aaltonen, T.; Mehtala, P.; Orava, R.; Saarikko, H.; Osterberg, K.; CDF Collaboration Contributor: University of Helsinki, Department of PhysicsUniversity of Helsinki, Helsinki Institute of PhysicsUniversity of Helsinki, Department of PhysicsUniversity of Helsinki, Department of PhysicsUniversity of Helsinki, Department of Physics Date: 2010 Language: eng Number of pages: 27 Belongs to series: Physical Review D : Particles, Fields, Gravitation and Cosmology ISSN: 1550-7998 URI: http://hdl.handle.net/10138/24429 Abstract: 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 $p\bar{p}$ 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 techniques that significantly reduce instrumental backgrounds in channels with an electron and missing transverse energy.
