Just catching up with this thread but I agree with everything said previously about not showing normalised XSecs.

This slide is looking very nice. Really great work being done by our dilepton group!

Thanks Richard!

The plot demonstrates that we have data from proton, neutron and for different decay modes.

It is different from Gluex and Hall-C. All data are compatible with each other. In my view it is good plot to present.

Thanks again,

Valery

Hi all,

Here's the plot Valery mentioned, let me know if you would change anything else.

Cheers,
Richard

Richard has very impressive plot (attached) with data on:

  *   p (bound)
  *   n(bound)
  *   p(free)
  *   p(mu+mu-)

We can ask Richard to remove Hall-D and Hall-C data, remove absolute value of cross section and present only CLAS12 without normalization (omega=1) for example.

Regards,

Valery

OK, I agree with Valery, we should not show the cross section comparison plot.

Here is the mail of Latifa.

We can remove the cs plot and keep the rest if you think it is better

Dear All,

I am writing to request one slide in the format of the attached template summarizing the status and next steps of your analysis. This information is for Patrick's presentation to the Lab's management next Tuesday February, 7th.

Please send me your slides by Monday February 6 at noon.  Let me know if you have any questions.

Best regards,

Latifa

Hi Pierre,

Do you know were this slide will be shown?

One thing you may want to add is the issue seen in BG merging in MC, with a statement that it may account for a large fraction of the discrepancy.

Regards, Stepan

Hello all,

Lafifa asked me for one slide summarizing the status of the Jpsi analysis.

I attached a first version to this email. Please let me know your comments and feedbacks. Especially, I am not sure if we should show the cross section yet.

Best

Pierre
