[PRad] [EXTERNAL] Re: Presentation for the CLAS Collaboration Meeting

[Jingyi Zhou]

Hi Patrick,

Thanks for your questions.

The plot on page 4 is from Fig.3 of this paper, I added the reference to the slides now.
https://urldefense.proofpoint.com/v2/url?u=https-3A__arxiv.org_pdf_hep-2Dph_0612014.pdf&d=DwIFAg&c=CJqEzB1piLOyyvZjb8YUQw&r=V3XNY-MaMKN2LuAaTdObrA&m=fjc6wSw1ccOroH1CcmaWOypbh5JkQ5Tv8WdTsFpuVGBaAWGOK7BWM3HEXqd-CCGZ&s=icDqYUhgyynbQS5CXecEdJdr3nOEmBYrU6pcQvOyr4A&e= 
It is an example demonstrating the Rosenbluth separation technique. Data points are shown for the Q2 values of 2.5 (open triangles), 5.0 (open circles) and 7.0 (filled triangles) (GeV/c)^2 . The straight lines are linear fits to the corresponding data points.

I am confused about your question on p.17. I don't have any references on p.17.

I also changed that to "proposal" on p.23.

Best,
Jingyi

Dear Jingyi,

thanks for the nice slides. I have a few comments:

I don't fully understand your plot on page 4.
- Which data set is plotted there? Is this from PRad? No reference is given.
- Why are the values between 7 and 9? Is this in per mille? The differences of any cross section data form the standard dipole form are maximum of 2-3 %.
- What is the Q2-value for the three different data sets?

I also don't quite understand the references to the tagger on p. 17. The tagger is not operational. I have not seen a request to upgrade the tagger in the DRad proposal.

On p. 23 I would call the DRad a "proposal", in line of what Ashot was discussing.

Best,
Patrick
