Query: Hybrids as a Signature of Quark-Gluon Plasma   We show that the dynamics of the Quark-Gluon Plasma is such that during
hadronization the creation of hybrids will predominate over the creation of
mesons, giving a novel signature of the existence of QGP. At T = 0 the
$(q\bar{q}g)$ hybrids are known to decay strongly into a pair of mesons. We
find that at temperatures relevant to the QGP, this channel is forbidden. This
would lead to significant modifications of the photonic signals of the QGP.
