[clas12_rgk] [Hybrid baryons] Slides for Tomorrow - run group K update

Thu Jul 12 11:50:57 EDT 2018

Dear Latifa,

thank you for your suggestions.

1.I will keep the physics part in the first 5-7 minutes.

2. Requirements from the physics to the experimental set-up are:

- Q2 vs W coverage (13-15)

- good energy resolution to separate K Lambda and K Sigma Channels 
(slides 18-19)

- reasonable acceptance to accumulate enough statistics in the widest 
phase space possible (slides 20 and 23)

3. Experimental set-up: slides 10 - 12, 21.

4. Simulation so far: slides 15, 19, 20, 22, 23, 25, 26

5. Simulation to be completed: detached vertex reconstruction (software 
tools are not available yet to complete the task)
We are trying to analyze results from 6.4 GeV and 10 GeV runs.

6. Computer requirements: slide 28

7. Manpower: I have explicitly added the task leaders and Lucilla's 
name. PhD students are to be assigned. The analysis coordinator has not 
been discussed yet. It is likely one of the spokespersons.

8. Expected physics: 11 M KY events

We will likely be available each time electron beam energy in CLAS will 
not be at the maximum.

I hope
