Query: Spin and parity of a possible baryon antidecuplet   The recently postulated existence of a baryon antidecuplet [1] can be
reproduced in strong coupling theory in which a bare baryon spin 1/2 octet
interacts with an octet of pseudoscalar mesons. When a suitable mixture of F-
and D-type Yukawa couplings is chosen the dressed baryons group themselves into
an infinite number of SU(3) multiplets of which the ground state turns out to
be a spin 1/2 baryon octet and the first excited state is a spin 3/2 baryon
decuplet. Then follows a spin 1/2 baryon antidecuplet. All states of the
spectrum have positive parity. If the hypothetical baryon antidecuplet can be
identified with the antidecuplet in the strong coupling spectrum then a
positive parity and a spin 1/2 is predicted for this multiplet.
