Massive Spinors and dS/CFT Correspondence

Using the map between free massless spinors on d+1 dimensional Minkowski spacetime and free massive spinors on $d{S}_{d+1}$, we obtain the boundary term that should be added to the standard Dirac action for spinors in the dS/CFT correspondence. It is shown that this map can be extended only to theories with vertex $(\bar{\text{p}}\text{p}{)}^2$ but arbitrary $d\ge 1$. In the case of scalar field theories such an extension can be made only for $d=2,3,5$ with vertices ${\varphi }^6$, ${\varphi }^4$ and ${\varphi }^3$ respectively.
