<br>
I wanted to make another suggestion for a talk/speaker. Namely, COMPASS has published (PRL announced to come out next week) the pion polarizability with good precision. In addition, COMPASS had published dynamics of 3pi production at low masses and shown that it fits nicely to a detailed description of this process in 5D phase-space by ChiPT. We expect to also present the same process with 2 neutral pions in the final state, which probes the importance of loop corrections, within 2015. I thus think that an overview talk on ChiPT related experiments (not only COMPASS) would be suitable. One candidate speaker, who has pushed the corresponding COMPASS program and who understands the subject at depth is J. Friedrich (TUM). I am not sure about the status of the present program, but it could be a nice complement for low energy QCD.<br>
<br>
With kind regards<br>
Stephan<br>
