nope
Photons are massless, massless particles travel at C.... Photons, however can create matter- like electron positron pairs....
Neutrinos were once thought to be massless... recent studies indicate that they do have mass...so they travel slower than C. Gravitons are massless and thus also must travel at C.
If you had enough photons concentrated in a small enough volume they would create a gravitational field- since in einsteins equations it is the energy/matter density that curves space-time......
Least that is what I remember from my general relativity course....
