As noted above, the apparatus is large enough to have sensitivity to neutral
states for all the runs listed above. Runs A and B, which use only the multiplicity
trigger, will be sensitive to all masses. Runs C and D, which use the late
energy trigger, will not have full sensitivity for low masses such as the H 
, but
will have full statistical sensitivity for higher mass states. Without the rejection from
the tracking system, it is expected that the sensitivity for neutrals will be limited
by background. The background is expected to fall as the mass increases. We have
shown above that in the mass region of the H dibaryon searches at the level of
10-3 per central interaction should be possible. For higher masses, the background
falls by about one order of magnitude per 1.5 GeV/c 
of increased mass.
