Hi Silvia,
Here are some comments:
- slide 2, “DVCS et al.”, I am not sure what this means, I think it should be just “DVCS”
- slide 3, better to have some explanations for “inbending” and “outbending”. For example, you could continue the “title” of bullets as “ … 3 different beam energies, and two orientations of the CLAS12 torus magnetic field, inbending and outbending electrons)”.
- slide 4, is it right to quote the luminosity “per nucleon”? all our measurements are related to either proton, neutron or deuteron. So the luminosity on these targets is half of the quoted number.
- slide 4, Richard’s J/psi results are from Pass2
- slide 5, the comment about the complementarity of nDVCS and transverse pDVCS - I am not sure this is correct. In each case, you mesure different quark combinations, and if you want to do flavor separation, you need both measurements nDVCS and transverslly polarised pDVCS.
- slide 5, I am not sure I understand why you are showing Hall-A data
- slide 7, can we write the fit function to the asymmetries, the blue line?
- slide 9, the same as above, the fit function. Valeri already commented, I agree that the table is not useful
- slide 10, there is space to write some explanations for the plots, for example, what are red bands?
- slide 12, a first bullet should explain that neutrons are detected and identified in the CLAS12 forwad calorimeters
- slide 21, should we say that with improved software will allow us to run at somewhat hiher luminosity?
Regards,
Stepan
