¥As of yet, the source of
the correlations has not been identified.
¥This is
what we know:
¥No
problems for Au + Au
¥No
problems for beam-gas events
¥Correlations
for d Au collisions
¥Correlations
are not present in the MC data
¥What do
these observations have in common?
¥Events
with a large number of primaries look OK
¥Events
for which there is significant probability of seeing no primaries show
correlations.
¥What are
we going to do?
¥In
parallel to continuing studies of the data collected, a number of experts are
looking at the hardware.
¥I plan
to switching to TOF integration next week, using the collision time of the ORs
to correct for the START jitter.
