Lei,
OK, I've edited the beginning a bit to reflect your comments.

Almost half a century after the prediction and discovery of the $\Omega^-$
baryon, many properties of the $S=-2$ and $-3$ hyperon  resonances remain
unknown. In particular, quark-model predictions suggest there are many more
Cascade states than have been seen in experiments. Recent theoretical
modeling indicates photo-production to provide access to these states and
their observables. The CLAS detector, part of JLAB's 6~GeV program, has
provided a unique lens into photo-production of the lowest mass Cascade
states at threshold, however the energy and luminosity reached was not
sufficient to study the heavier $\Xi^*$'s or the $\Omega^-$. With the
increased energy and better charged-kaon identification promised with
CLAS12, we propose to study the production mechanisms of $S=-2, -3$ baryons
with high precision and statistics in exclusive photo-nuclear reactions.
