  We propose to interpret the possible resonance seen in di-photons at the LHC
at 750 Gev as a bound state of a new pair of heavy gluons associated with an
enhanced color gauge invariance. These have a conservation law which enforces
their production and decay in pairs and hence requires that the leading
coupling to quarks is quadratically through a dimension 5 operator. One way to
realize these hypotheses is if the SU(3) color gauge invariance is enhanced to
SL(3, C), while at the same time promoting the internal metric, which picks out
what is a unitary transformation, to a dynamical degree of freedom. This theory
was first proposed by Cahill[3], Dell[4], Kim and Zee[5], and Julia and
Luciani[6]. The dynamical internal metric spontaneously breaks SL(3,C) to SU(3)
giving a mass to the vector bosons associated with the generators in
SL(3,C)/SU(3). The coupling to the internal metric also ensures that the energy
is bounded from below. The new state is produced by gluon fusion and decays to
a pair of photons via a direct coupling to a new set of vector quarks allowed
by the symmetries.
