Summary

•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.
