Abstract

Quantum discontinuity between zero and infinitesimal graviton mass with a λ term was studied. The one loop graviton vacuum amplitude was also caculated for a massive graviton. The results showed that the absence of the discontinuity is only an artifact of the tree approximation and the discontinuity reappears at one loop.
