| dc.description | 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. | |
