Hi Mike,<br>
The consistency is good now at least. And if you detect the K-
too the situation is actually quite promising as the background
seems to be entirely suppressed by a vertex cut.<br>
Cheers<br>

Hi,
<br>
<br>
I have now found the answer to my original question as to whether
my Omega plot looked reasonable.
<br>
<br>
The problem: The cross section weighting for the Omega- was too
large when I simply scaled the neutral cascade cross section by
1/10. The effective cross section I reported earlier was measured
after the detection efficiency, so it was just dumb luck that the
effective cross section ended up near the value that we wanted
BEFORE the simulated detector response.
<br>
<br>
I put in 0.3 nb for the Omega- cross section (as Igor requested)
and got the plot attached (OmegaMNew.gif).
<br>
<br>
The bad news: The Omega- signal I get is consistent with Derek's
and is a sad little guy :(
<br>
<br>
Take care,
<br>
Michael
