Query: A search for direct heffalon production using the ATLAS and CMS
  experiments at the Large Hadron Collider   The first search is reported for direct heffalon production, using 23.3/fb
per experiment of delivered integrated luminosity of proton-proton collisions
at rootS = 8TeV from the Large Hadron Collider. The data were recorded with the
ATLAS and the CMS detectors. Each exotic composite is assumed to be stable on
the detector lifetime (tau >> ns). A particularly striking signature is
expected. No signal events are observed after event selection. The cross
section for heffalon production is found to be less than 64ab at the 95%
confidence level.
