Decomposing the $\mathcal{N} = 4$ massless graviton supermultiplet
I'm trying to solve the following exercise:
Construct the physical states of the $\mathcal{N} = 4$ massless graviton supermultiplet, starting from a Clifford vacuum of helicity $λ_0 = 0$.
Decompose ...

Is N=6 SUSY gravitino multiplet self-CPT?
I would like to understand why the $N=6$ gravitino (massless) multiplet
$$\left(-\frac32,(-1)^{6},(-\frac12)^{15}, 0^{20}, (+\frac12)^{15}, +1^6, +\frac32 \right)$$
is not CPT self-conjuguate?. It ...

$\mathcal{N}=2$ susy hypermultiplet self-CPT?
Is the multiplet given by
$$\left( -\frac12,0,0,\frac12 \right)$$
self-CPT conjugate?
There seems to be no common agreement upon that:
Weinberg (QFT 3, page 47) and many others claim it is not, ...
