Although I would support that proposal as a new CLAS12 experiment, the fact that you are still discussing prominently the "The need for inbending.." is a distraction and will only confuse the collaboration and the PAC, should it be submitted as a RGK run group
proposal extension. I am therefore unable to join the proposal. </div>

those energies in the 4 pass and in 3 pass operation. That's why we have to settle on the somewhat lower energies.</span><br>

<b>Subject:</b> [EXTERNAL] Run group addition proposal</font>
<div> </div>
</div>
<div>
<div dir="ltr">Dear All,
<div>While we are still working on the part with RGK data the draft has some details on MC and the motivation. The latest version is in <a href="https://userweb.jlab.org/~avakian/tmp/Run_Group_K_Proposal__LT_separation_of_the_SIDIS_pi__cross_section.pdf" data-auth="NotApplicable">https://userweb.jlab.org/~avakian/tmp/Run_Group_K_Proposal__LT_separation_of_the_SIDIS_pi__cross_section.pdf</a></div>
<div>We make the case for 8.4 (better 8.8) being critical for Q^2>4 GeV to qualify for run group addition.</div>
<div>We will need relative cross section measurements with systematics below 5%.</div>
<div>We do have some estimates of expected cross sections. For better understanding of opportunities with exclusive parts it will be useful to have some evaluation of expected x-sections for some bins vs beam energy.</div>
<div><br>
</div>
<div>Please let me know if you will be interested to be part of the proposal.</div>
<div>Best regards,</div>
<div>Harut</div>
<div><br>
</div>
<div>P.S. We may push for online reconstruction in future to be used in online monitoring of tracking efficiencies in the full kinematics in polar and azimuthal angles of electrons.</div>
