Query: E6 inspired composite Higgs model   We consider a composite Higgs model embedded into a Grand Unified Theory(GUT)
based on the E_6 gauge group. The phenomenological viability of this E_6
inspired composite Higgs model (E6CHM) implies that standard model (SM)
elementary fermions with different baryon or lepton number should stem from
different 27 representations of E_6. We present a six-dimensional orbifold GUT
model in which the E_6 gauge symmetry is broken to the SM gauge group so that
the appropriate splitting of the bulk 27-plets takes place. In this model the
strongly coupled sector is localised on one of the branes and possesses an
SU(6) global symmetry that contains the SU(3)_C\times SU(2)_W\times U(1)_Y
subgroup. In this case the approximate gauge coupling unification can be
attained if the right-handed top quark is a composite state and the elementary
sector involves extra exotic matter beyond the SM which ensures anomaly
cancellation. The breakdown of the approximate SU(6) symmetry at low energies
in this model results in a set of the pseudo-Nambu-Goldstone states which
include a Higgs doublet and scalar colour triplet. We discuss the generation of
the masses of the SM fermions in the E6CHM. The presence of the TeV scale
vector-like exotic quarks and scalar colour triplet may provide spectacular new
physics signals that can be observed at the LHC.
