Abstract:

We have searched for a heavy resonance decaying into a Z+jet final state in pp̄ collisions at a center of mass energy of 1.96TeV at the Fermilab Tevatron collider using the D0 detector. No indication for such a resonance was found in a data sample corresponding to an integrated luminosity of 370pb-1. We set upper limits on the cross section times branching fraction for heavy resonance production at the 95% C.L. as a function of the resonance mass and width. The limits are interpreted within the framework of a specific model of excited quark production. © 2006 The American Physical Society.

Abstract:

We present results of a search for anomalous production of events containing a charged lepton (l, either e or μ) and a photon (γ), both with high transverse momentum, accompanied by additional signatures X, including missing transverse energy (ET) and additional leptons and photons. We use the same selection criteria as in a previous CDF search but with a substantially larger data set, 305 pb-1, a pp̄ collision energy of 1.96 TeV, and the CDF II detector. We find 42lγET events versus an expectation of 37.3±5.4 events. We observe 31 γ+X events versus an expectation of 23.0±2.7 events. We find no events similar to the run eeγγET event. © 2006 The American Physical Society.
