The (m2,Lambda) plane of spin s>1 massive fields in (anti-) de Sitter space backgrounds is shown to consist of separate phases, divided by lines of novel "partially massless" gauge theories that successively remove helicities, starting from the lowest, 0 or +/-1/2. The norms of the excluded states flip as the gauge lines are crossed and only the region containing the massive Minkowski theory is unitary. The partially massless gauge theories are unitary or not, depending on the ordering of the gauge lines. This "level splitting" of massless Minkowski gauge theories is specific to nonzero Lambda.
在（反）德西特空间背景下，自旋(s>1)的大质量场的((m^2,\Lambda))平面被证明由不同的相组成，这些相被新颖的“部分无质量”规范理论的线分隔开，这些规范理论从最低的螺旋度(0)或(\pm1/2)开始依次去除螺旋度。当穿过规范线时，被排除态的范数会翻转，并且只有包含大质量闵可夫斯基理论的区域是幺正的。部分无质量规范理论是否幺正取决于规范线的排序。这种无质量闵可夫斯基规范理论的“能级分裂”特定于非零的(\Lambda)。
