Abstract:
Prompted by an observation by Vladimir, we show that the
effective emittance lifetime is slightly (15% effect, relative to the total luminoisty lifetime), albeit signficantly on a statistical basis, higher than the combined ("average") of emittance growth reported by the Sync Lite and the SBD. The source of this discrepency is unknown

Also in this document is a talk presented at a RunII meeting where a Luminosity lifetime check - sum similar to those recomputed in this work, is shown. The deficiency in effective transverse emittance growth was already present at that time although not very statistically signficant
