Third Circular
Dear Colleagues,
Thank you once again for your participation in the 3rd Proton Mass Workshop. We think it is fair to say that we had outstanding presentations which lead to many insightful and productive discussions. It is clear that there is considerable interest in this topic and that significant progress is being made to better understand the proton mass.
It is therefore timely to write a community white paper on the proton mass and we would like to reiterate our call for contributions. We ask all those interested to email us a write-up of at most one page:
- This one page includes text and figures but not references
- Please use Latex with the standard INSPIRE reference format (ideally bibtex)
- Please send these contributions to Ian Cloët ([email protected]) by the end of this month (31 Jan 2021)
- Everyone that sends a contribution is invited to be an author of the white paper.
The Editors for this white paper:
Constantia Alexandrou, Ian Cloët, Xiangdong Ji, Dima Kharzeev, Andreas Kronfeld, Zein-Eddine Meziani, Barbara Pasquini, Jen-Chieh Peng, Jianwei Qiu, and Marc Vanderhaeghen
will then take these contributions and create a first draft with a tentative time line of summer 2021. We will then make the draft publicly available and organize and open meeting to discuss the draft. We then plan to publish soon after the 4th proton mass workshop to be held at the INT in December 2021.
We look forward to your contributions and to continuing this discussion on the proton mass at future meetings.
All the best,
Ian Cloët, Xiangdong Ji, Zein-Eddine Meziani, and Jianwei Qiu
Second Circular
Dear Colleagues,
Just a gentle reminder that for those interested the "3rd Proton Mass Workshop: Origins and Perspective" will be held remotely on 14-16 January 2021. If you have not done so already we invite you to register at
https://indico.phy.anl.gov/e/mass2021
Please do this by Tuesday evening (today) as we will send all registered participants the Zoom link and password for the workshop on Wednesday morning.
In addition to the invited presentations we also invite short (5 minute) contributions from participants, to be presented during the discussion sessions. If you would like to present such a contribution please send at most a few slides to Paula Dahlberg <[email protected]> as soon as possible, indicating in which discussion session you would like to present your slides.
The first circular for this workshop can be found on the workshop website, and we look forward to your participation.
All the best,
The Organizers:
Ian Cloët (Argonne National Laboratory)
Xiangdong Ji (University of Maryland)
Zein-Eddine Meziani (Argonne National Laboratory)
Jianwei Qiu (Jefferson Lab)
First Circular
Dear Colleague,
We invite you to participate in the "3rd Proton Mass Workshop: Origins and Perspective" which will be held remotely on January 14-16, 2021. The workshop will explore questions about the origin of hadron masses and confinement within Quantum Chromodynamics. If you are interested in participating please register at
https://indico.phy.anl.gov/e/mass2021
Participation will be via Bluejeans, and all registered participants will receive the meeting link and password via email on Tuesday 12 January 2021.
A goal of the workshop is to place on firm ground well-posed fundamental questions that can be addressed worldwide with measurements of well-defined observables, including at Jefferson Lab and the EIC. The question "How does the mass of the nucleon arise" is one of the triad of National Academy of Science questions supporting the EIC science case. The answer to this question has far-reaching consequences for our deep understanding of the universe's visible matter and perhaps beyond. Since, as we look to nature for unique confined systems where most of the mass is provided by the energy of its fields, two examples come into mind, protons and black holes.
We also invite participants to contribute a few slides that articulate your perspective on topics related to this workshop, perhaps by addressing one of the posed questions or providing a new question to consider. These slides will be posted to the workshop website and time permitting be selected for 5 minute presentations during the discussion sessions. Please send these contributions to Paula Dahlberg <[email protected]>, preferably by Monday 11 January 2021.
By the end of the workshop, we would like to converge on a few fundamental science questions and identify corresponding observables to be measured to add to our understanding of the proton mass and confinement. To make the discussions productive and efficient, we'll do our best to post the invited presentations a week before the start of the workshop for every participant to engage in the discussion and formulation of the critical questions. We aim at producing a community white paper on the subject of this workshop, as it pertains to the vast majority of the visible matter in the universe.
Looking forward to your participation.
Happy Holidays!
