Dear Mike and friends of the IAC: <br>
Rarely a suggestion for a meeting finds such enthusiastic backing as
the idea of Alberto. <br>
Let me add that such topic has also raised much interest in the
theoretical community recently and is catching up. Reporting on
this in the meeting will be most opportune.<br>
<br>
Cheers<br>
<br>

Dear colleagues,

<div>Indeed, the issue is very relevant for heavy flavour decay. I
would, however, avoid a logical direction for this session but
rather call it: </div>
<div><br>
</div>
<div>"Heavy meson decays and the light meson spectrum“ or

Subject: Re: [Iac_hadron_2015] Recommendations
Hadron<br>
<br>
Dear colleagues,<br>
<br>
in the past fifteen years decays of D and B mesons
have been playing an<br>
important role in hadron spectroscopy. While
primarily focused on Flavor Physics,<br>
experiments such as E791, FOCUS, CLEOc, BES,
Belle, BaBar, LHCb provided<br>
many important measurements and discoveries: the
sigma, the kappa, and<br>
other measurements that helped the understanding
of the nature of the light<br>
scalars; the DsJ, the new XYZ hadrons, among other
contributions.<br>
<br>
In recognition, in past editions of this
conference series we had sessions like<br>
"Light quark spectroscopy from heavy meson
decays". In what concerns the<br>
spectroscopy of light hadrons, I believe it is
time to change the direction of the arrow.<br>
<br>
The ongoing experiments have collected very large
samples of heavy meson<br>
decays. Soon a new generation of experiments will
be commissioned. This brings<br>
us to a precision era in Flavor Physics. However,
to fully exploit the potential of this<br>
large amount of very good data, performing
accurate measurements of the CKM<br>
elements, mixing parameters, CP asymmetries, new
Physics searches, the input<br>
from the hadron community is extremely necessary.<br>
<br>
The theoretical and experimental progress in our
understanding of two-body<br>
systems must be incorporated into the many-body
environment of hadronic<br>
B and D decays, in a systematic and consistent
way. A better understanding of<br>
the connection between quark and hadron degrees of
freedom is also in order,<br>
a necessary ingredient for sound parameterizations
of nonresonant amplitudes.<br>
FSI is a complex subject, involving three- and
four-body interactions, but it should<br>
also be taken into account. The application of
fundamental principles and<br>
symmetries, constraining the decay amplitudes is
another issue: in decays of<br>
B_u mesons into three light hadrons, where CP
asymmetries reach up to 80%<br>
in regions of the phase space, FSI may couple
different decay channels, such<br>
as B+->K+K-K+ and B->K+pi-pi+, in a
beautiful realization of the CPT symmetry.<br>
<br>
Before this becomes a manifesto, let me propose a
parallel session dedicated<br>
to these subjects, a session containing both
theory and experimental talks. There<br>
has been some scattered and disconnected
initiatives in this direction. I think the<br>
Hadron conference would be a very appropriate
occasion for such discussions.<br>
<br>
With my best regards,<br>
Alberto.<br>

Dear all<br>
<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>

The photoproduction of the Lambda(1405) is done by
Schumacher and Moriya, although it has been
reported in may places already. On the lab issues
you can make your own selection.<br>
