Search for Photon + b jet + jet + MET at CDF
Public Page |
|
We present a signature-based search for 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. The
search uses data corresponding to 2 fb-1 of integrated luminosity.
We find 617 events with MET > 25 GeV and two jets with Et> 15 GeV,
at least one identified as originating from a b quark, versus an expectation of
637 +- 139 events. We report observed event counts for this signature and for
additional objects, standard model background predictions, and kinematic
distributions. We find no indications of non-standard model phenomena.
