The particle spectrum of de Sitter is different from that of flat space. There exist special, discrete states in dS whose behavior lies somewhere between that of the massive and massless fields we are familiar with in Minkowski. I will discuss the signatures that such "Partially Massless" fields would leave on inflationary correlators, highlighting particularly clean detection channels. The calculation will be phrased in terms of the "Wavefunction of the Universe", a practical tool for computing expectation values whose details will be familiar to those who have worked with holography.
