abstract = {A search is performed for the process
pp→G⁎→BHb¯/B¯Hb→Hbb¯→bb¯bb¯ , predicted in
composite Higgs scenarios, where G⁎ is a heavy colour
octet vector resonance and BH a vector-like quark of charge
−1/3 . The data were obtained from pp collisions at a
centre-of-mass energy of 8 TeV corresponding to an
integrated luminosity of 19.5 fb−1 , recorded by the
ATLAS detector at the LHC. The largest background, multijet
production, is estimated using a data-driven method. No
significant excess of events with respect to Standard Model
predictions is observed, and upper limits on the production
cross section times branching ratio are set. Comparisons to
the predictions from a specific benchmark model are made,
resulting in lower mass limits in the two-dimensional mass
plane of mG⁎ vs. mBH .},
