Phys. Rev. D 69, 107501 (2004) [3 pages]Photon mass and gravitational deflectionReceived 16 December 2003; published 17 May 2004 The deflection of a massive photon by an external gravitational field is energy-dependent. Interesting enough, any massive quantum particle, no matter what its spin is, undergoes dispersive deflection in external gravitational fields. Exploiting the dispersive deflection of the quantized massive electromagnetic radiation by the gravitational field of the Sun, we find an upper bound for the photon mass. © 2004 The American Physical Society URL:
