Search for anomalous production of events with a photon, jet, b-quark jet, and missing transverse energy
We present a signature-based search for the anomalous production of events containing a photon, two jets, of which at least one is identified as originating from a b quark, and missing transverse energy (E̸[subscript T]). The search uses data corresponding to 2.0 fb[superscript -1] of integrated lu...

| description | We present a signature-based search for the anomalous production of events containing a photon, two jets, of which at least one is identified as originating from a b quark, and missing transverse energy (E̸[subscript T]). The search uses data corresponding to 2.0 fb[superscript -1] of integrated luminosity from pp̅ collisions at a center-of-mass energy of √s=1.96 TeV, collected with the CDF II detector at the Fermilab Tevatron. From 6.697 47×10[superscript 6] events with a photon candidate with transverse energy E[subscript T]>25 GeV, we find 617 events with E̸[subscript T]>25 GeV and two or more jets with E[subscript T]>15 GeV, at least one identified as originating from a b quark, versus an expectation of 607±113 events. Increasing the requirement on E̸[subscript T] to 50 GeV, we find 28 events versus an expectation of 30±11 events. We find no indications of non-standard-model phenomena. |
