I have been looking over the internet for a resource that tells me the number of dimensions of a spin $s-1$ spinor representation of $SO(d+1,1)$, but unfortunately have yet to be able to find it. In some sense, this dimension also tells us the dimension of a rank $s-1$ Killing spinor of $SO(d+1,1)$.
