Abstract: (NRC Research Press)
Filling a much-needed gap, we exhibit the D = 4 Fierz–Pauli massive s = 2 action, and its — manifestly positive — energy, in terms of its 2s + 1 = 5 unconstrained helicity (2, 1, 0) excitations, after reducing and diagonalizing the troublesome helicity-zero sector.- 11.10.-z
