22 GeV Open Discussion

The goal of the 22 GeV Open Discussion meetings are to discuss and refine the scientific case for the 22 GeV upgrade. These discussion are likely to build on the ideas in the 22 GeV White Paper but are also a good place to bring new ideas.

Eventually we will need to lay out the most compelling scientific arguments for the 22 GeV upgrade in order to secure the support of the community and ultimately the funding agencies. Therefore we want to raise and examine all potential criticisms in advance in order to strengthen the scientific case. We anticipate these discussions to motivate additional studies or simulations needed demonstrate the impact of various measurements.

Guidance for Speakers

The goal for speakers should be to provoke discussion from the group which has broad scientific interests in nuclear physics as well as being composed of both theorists and experimentalists.

Aim for 15 minutes of presentation followed by discussion. This should be 3-5 slides maximum. Additional backup slides can be included for anticipated questions. The goal is to get the discussion started.
Focus on three things for each measurement:
1. the broader context and motivation for this particular measurement
2. a description of what is being measured and the anticipated precision or sensitivity
3. the importance of 22 GeV electrons
It may be helpful to think about broad questions in the context of the scientific method like
- What falsifiable hypothesis is being tested by the measurement?
- What precision is required to draw a conclusion from the result?
- Do the results lead to an understanding of nature that is predictive in some way?
- Based on the result what predictions can be tested with future measurements?
As an expert you know the uncertainties, weak points, or challenges in the scientific arguments. Raise them in the discussion, and together we can strengthen the case or identify areas where additional study is needed.

Guidance for Participants

Critically evaluate the motivation and scientific arguments: critical discussion is necessary to develop a strong scientific argument.
Share the speaking time amongst the other participants and try to focus questions on topics that are likely to be of broad interest to the group.
Argue your point in a respectful and professional manner.

Meeting Coordinates

The meetings are scheduled for every other Monday at 12:30 PM Jefferson Lab local time. The conference room CC F224/5 has been reserved. The discussions will also be broadcast via Zoom Meeting Number 161 111 8017. The password for this meeting is the two-digit number that appears before "GeV" in the first sentence of this page.
