Query: On The Bound States Of Photons In Noncommutative Quantum Electrodynamics   We consider the possibility that photons of noncommutative QED can make bound
states. Using the potential model, developed based on the constituent gluon
picture of QCD glue-balls, arguments are presented in favor of existence of
these bound states. The basic ingredient of potential model is that the
self-interacting massless gauge particles may get mass by inclusion
non-perturbative effects.
