1) Dalitz plot analyses are beginning to be common in both BABAR and Belle.
There are a number of issues surrounding such analyses:
 a) Is it too late to suggest common conventions for DP amplitude definitions
   and other issues which will facilitate combination of results?
 b) What will we do about quoting branching fractions from DP analyses?
   Strictly speaking the branching fraction is not defined once one is doing
   full DP analyses due to issues surrounding overlap regions.  My own
   opinion is that it would be foolish to not derive some kind of quasi-2body
   BRs, even if the definition is somewhat arbitrary.  These Q2B BRs are of
   considerable interest to the theoretical community and it would seem
   bizarre to me to take the point of view that we can only provide BRs when
   we have datasets that are too small to do proper DP analyses.
  c) If we find structures in the DP that are not listed in PDG, what do we
   do about listing such results?  After all, there is much that isn't clear
   in pipi and Kpi spectroscopy below 2 GeV, especially for S-wave.  I
   believe it's clear that a contribution needs to be added to DP fits to
   account for experimentally observed features such as the f_x(1500)
   KK enhancement.  It's less clear what we should do about listing BRs to
   such states which are almost certainly some combination of missing or
   poorly understood resonances with unknown quantum numbers.

The rare sub-group thinks it useful for HFAG to consider this and to urge the
spokespersons of CLEO, Belle and BABAR to help form a committee of people
interested in DP analyses to address these issues and make recommendations.
This should happen as soon as possible - it is already a bit late.
