[EIC-exclusive] [EXTERNAL] RE: EIC/JLAB Exclusive processes meeting

[DEFURNE Maxime]

Dear Volker,

You may have a typo in your e-mail. The benchmark configuration for the lowest s is 5*41 and not 3*41.

In attachment, I sent you a study I have already started on the separation between dvcs and pi0. You must start with _0 document and finish with _1 document.

Kind regards,

Maxime

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
