Query: On massive higher spins in d=3   In this paper we consider a frame-like gauge invariant description of massive
higher spin bosons and fermions in d=3 and provide for the first time a proof
that such formulation does describe just one massive physical degree of freedom
with the appropriate helicity. For this purpose we completely fix all the gauge
symmetries and show that all other auxiliary components vanish on-shell, while
the only remaining highest component satisfies the correct equations. As a
bonus, we show that the Lagrangians for the so-called self-dual massive spin-3
and spin-4 fields proposed by Aragone and Khoudeir (as well as their
generalization to arbitrary integer and half-integer spins) can be obtained
from the gauge invariant ones by the appropriate gauge fixing.
