<div dir="ltr"><div>Dear Marshall,</div><div>To link it better to SPIN conference, where spin physics is basically used to understand the non-perturbative QCD through correlations of spins of initial nucleons and struck partons with transverse momentum and spins of scattered partons and final state hadrons, you can add a sentence on that. It is straightforward to make the case that when you detect the hadron in the final state all SIDIS interpretation becomes spin-dependent as there are no "unpolarized" quarks and contributions of different spin states will change in general with the hadron transverse momentum, which depends on the quark transverse momentum, which depends on the spin orientation of the quark.</div><div>In addition I suggest adding a sentence before "This work...." to emphasize the importance of pi0 production studies in SIDIS. Something like</div><div>"Neutral pion production, unlike charged pion case, is not expected to have any major physics backgrounds, such as diffractive vector meson, semi-exclusive hadron production, or longitudinal photon contributions, and can provide a unique tool to study direct production of hadrons." </div><div>Best,</div><div>Harut</div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, May 30, 2023 at 5:30 PM Sebastian Kuhn via Deeppwg <<a href="mailto:deeppwg@jlab.org">deeppwg@jlab.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

Deaer Marshall,

</div>
<div>I am not entirely sure what the relevance of this abstract is for a SPIN conference. IF you are measuring, e.g., beam spin observables, you should mention that in your abstract. Did you receive an invitation by one of the conveners, or is this
a contributed abstract? Which Parallel Session (topic) are you submitting it to?</div>
