Abstract

In a previous paper we showed that the absence of the van Dam-Veltman-Zakharov discontinuity as M2 → 0 for massive spin 2 with a Λ term is an artifact of the tree approximation, and that the discontinuity reappears at one loop, as a result of going from five degrees of freedom to two. In this Letter we show that a similar classical continuity but quantum discontinuity arises in the "partially massless" limit M2 → 2Λ/3, as a result of going from five degrees of freedom to four.
