Continuing our earlier work on the application of the Relativistic Generalized Uncertainty
Principle (RGUP) to quantum field theories, in this paper we study Quantum
Electrodynamics (QED) with minimum length. We obtain expressions for the Lagrangian,
Feynman rules and scattering amplitudes of the theory, and discuss their consequences for
current and future high energy physics experiments. We hope this will provide an improved
window for testing Quantum Gravity effects in the laboratory.
