[EIC-exclusive] EIC/JLAB Exclusive processes meeting

[burkert]

Dear all,

This is a reminder of our next EIC/JLab exclusive processes meeting 
Tuesday 4/14 at 10am.

At that meeting we should discuss a plan to develop our simulations for 
the DVCS => CFF => GFF procedure with the EIC - high x kinematics in mind.

Simulations would cover two cms energies sqrt(s) = 22.2GeV ( 3 GeV x 41 
GeV) and sqrt(s) = 45 GeV (5 GeV x 100 GeV). We should look at both the 
electron-spin asymmetries as well as the proton transverse polarization 
asymmetries and the longitudinal double asymmetries. If available we 
could use different event generators.

1) The first part would continue to study how well we can isolate DVCS 
from the pi0**production, and what is required in terms of detector 
energy resolution and angle resolutions for all measured particles with 
reference to the resolution assumptions as specified in the EIC detector 
handbook. The goal would be to make significant progress on this project 
by the time of the Pavia YR meeting in May.

2) We should also review were we are with the spectroscopy project 
(baryons or mesons), and if there are preliminary results that can be 
presented at the Pavia meeting.

3) For the longer term part we should look into how well we can 
determine the CFF H(xi, t), E(xi, t), and the gravitational form factors 
d1(t), J(t), M2(t) after data are taken at the kinematics as described 
above assuming data are taken with  10fb^-1 and with 100fb^-1, for each 
of the polarization combinations. For any simulations please use 
detector resolutions as described in the EIC  Detector Handbook table.

Please describe any DVCS/CFF event generator that may be available, or 
plans/status of developing one.

A tentative agenda (unconfirmed) is posted at 
https://jleic-docdb.jlab.org/cgi-bin/private/DisplayMeeting?conferenceid=12. 


Send your input into the agenda by Monday, and announce any contribution 
you may want to make.

Enjoy your weekend and holiday,


Charles & Volker
