Heng-Ye Liao - Elastic-Inelastic handling in protoDUNE proton data (Guest)

• CKJ: Slide 6: How do you define the interactions channels? HYL: From reconstuction. CKJ: How do you define vertex? HYL: We use pandora for the reconstruction and it looks for end points and then go backward along hits and it looks for kinks.
• CKJ: We don't understand why the track length can help us distinguish between inelastic and elastic scattering.
• CKJ: Slide 11: Changing ratio between elastic and inelastic as you go deeper in the detector, but it is not reflected in slide 12. HYL: Will discuss offline because I have to leave for another meeting.

 

Nataliya Skrobova - Gamma peak study

• GY: Just a clarification: she is using the data taken in 2020 with the configuration where SFGD exposed to beam directly.
• GY: missed question on slide 8
• GY: Is t0 0.8 ns? NS: Yes. MD: It is mostly the digitization resolution so if you have more channels of t0, that will help. GY: Yes, I should have 3 channels plugged in. I will send you my notes on this. DL: You can look at FEB12. MD: This would improve the resolution a lot.
• CKJ: Slide 12: What do you mean with 1 channel? GY: Is the t0 channel. That's the global t0.

 

Abraham Teklu - Time scale unceratinty study

• GY: Did you include the statistical error in the final cross section error plot? AT: Yes
• DL: That does not look right referring to the extinction curve you showed before
• MD: 1. with the time-walk correction plus the averaged timing calibration, we will have continuous timing, i.e. energy does not have to be cut off in this way. 2. Can you explain how you got the error again? AT: repeat the method MD: Why the change is so small in terms of the cross section error in the final plot. At high energy, timing resolution is about 1 ns and your bin size is about 2.5 ns. GY: The cross section at high energy is similar enough to not give you any difference in the cross section value.
