摘要
Using cohomological methods we determine the most general form of the interaction between the gravitational field and an arbitrary system of Yang-Mills fields (massless and massive). We solve the corresponding descent equations and obtain the first order chronological product (interaction Lagrangian). Surprisingly enough we find that gravitational ghost and Yang-Mills anti-ghost fields appear in the coupling in the massive Yang-Mills case.
