[clas12_rgk] [EXTERNAL] Message from Harut - New PAC review: 'Separation of the $sigma_L$ and $sigma_T$ contributions to the production of hadrons in hard lepto-scattering' by Timothy Hayward et al.

Tue May 2 09:02:03 EDT 2023

Dear Annalisa,

I know that K.Joo has an interest to get L/T separation from (e,e'X) inclusive data. I send him our Meeting link if he decided to participate in the discussion.

Best Regards,
                                                 Victor

Dear RG-K members,

I have received the attached e-mail from Harut about the use of Rg-K data to perform the L/T separation in SIDIS.

A proposal is going to be submitted to the next PAC, whose draft you may find in attachment.

Harut is inviting "RG-K people" to join the proposal.

We could start a discussion during tomorrow RG-K meeting.
All the best
Annalisa

Dear Dan and Annalisa,

Last few days were pretty hectic.  To fit the dead line, we submitted the draft of the proposal (see below) so far focused mainly on L/T separation in SIDIS,  to collaboration review.  The MC part is more or less done, we are working on the preliminary extraction of the R=L/T from data, which we hope to have within a week or so, to be ready for submission in May. Part of the work was done to understand the relevance of different configurations (kinematics, beam energies, inbending vs outbending) to maximize the impact of the future RGK run, and possibly motivate its extension.

Will be great to have in the proposal RGK people, in particular people involved in exclusive hadron production. I am pretty sure that proper  L/T separation in multi-dimensional bins  will be useful for DVCS community as well. We can coordinate the configurations we suggest for future running. What you think about having another combined meeting  of RGK with L/T SIDIS group within next two weeks to better coordinate our efforts?

Best regards,

Harut

Dear Silvia and committee members,

Please find the first draft of our proposal at the following link: https://clas12-docdb.jlab.org/cgi-bin/DocDB/private/ShowDocument?docid=1078. We anticipate making updates to further flesh out some of the details over the coming days but the majority of the content is available. Thank you again for accepting to review the proposal.

Best regards,
Timothy
