The Proton Mass: At the Heart of Most Visible Matter

Aula Renzo Leonardi - Villa Tambosi

Str. delle Tabarelle, 286, 38123 Villazzano TN

At the conclusion of a small two-day workshop held on March 28-29, 2016 at Temple University ( to explore the origin of the proton mass a consensus emerged from the participants and that is to follow-up this short workshop with a week-long workshop. The goal is to involve a larger community to investigate and expand on a set of findings of the first workshop where a three pronged approach to the problem of the proton mass was identified. It was clear that the subject of the mass decomposition of hadrons in terms of their constituents is of paramount importance and of interest to a broad audience and thus deserves closer attention. Its impact on our communication of hadron/nuclear science goals to the wider physics community as well as the public has far reaching consequences. The goal of this proposal is to bring more experts around the world to join the effort to explore the origin of the proton mass, and to expand the discussion of the short workshop held at Temple. Furthermore, in light of the upcoming science evaluation by the US National Academy of Science of the Electron Ion Collider project, a nuclear/hadronic physics facility endorsed in the 2015 US nuclear science long range plan as the next construction project after the completion of FRIB, it becomes even more important to articulate the physics impact of such a machine, among them our quest to understand the basic properties of the nucleon, responsible of most visible matter in the universe, in terms of its basic constituents. Having this focused workshop in the Spring 2017 at the European Centre for Theoretical Studies in Nuclear Physics and Related Areas (ECT*) in Trento (Italy) is not only timely, but also at an ideal setting to get a broader audience involved.
