  The new recently experiments at the B-factories yield a renewed interest in
the charm and charmonium spectroscopy. New intriguing states have been
observed, which appear to be non-conventional mesons, such as X(3862) and
Y(4260) and request more theoretical investigations. We will explore the
possibility for the Y(4260) to be a c-cbar-g hybrid meson. Using the
quark-gluon constituent model, we exclude its existence as QE-hybrid meson, and
as mixing of c-cbar-g hybrid with conventional c-cbar meson. We find the only
interpretation as GE-hybrid, decaying in D_(1)-Dbar channels. Then more
experimental studies are needed to confirm the existence of this resonance and
to give its properties.
