Debbie,
"It is very frustrating that someone with an ID-capable detector didn't collect something." That is not a given. There could easily have been data collected but not disclosed. Celani may have been covering his tracks with what seems to be a persistent effort to explain to journalists on several occasions how he was frustrated to make this measurement - when in fact it could have been done, prior to - or following the main activity. All of Celani's recent papers have been on Pd-D systems. It will be interesting in the coming weeks to see if he should come out with something different. in response to what he may, or may not have learned. That goes for others as well. ". oh, it was just a lucky guess" <g> Jones
