Real scalar field, EM field and Dirac field can be quantized in gravity. The equation of motion in each field will contain a 'gravitational' covariant derivative that will produce new energy-momentum dispersion relation. The dispersion relation in each case preserves the old energy accompanied with a perturbed term. The mathematics of the field quantization will remain unchanged with additional energy perturbation due to interaction with spacetime curvature. The correction of Dirac Lagrangian due to gravitational covariant derivative will lead to the probable existence of the gravitational gauge field, an analog to the EM gauge field.
