The JAM collaboration involves theoretical physicists, experimental physicists, and computer scientists from the Jefferson Lab community using QCD to study the internal quark and gluon structure of hadrons. The people involved in recent and ongoing JAM analyses include:
Vision: Partnering with our customers, we provide support to further the laboratory's mission to operate a world class user facility for conducting nuclear physics research. Our focus is to provide project management and integrated planning support across the Lab that is aligned with Lab goals, objectives and guidance.
The Chief Planning Officer coordinates and manages the allocation of laboratory resources and budgets across the divisions, including internally and externally funded projects, and facilitates development of the laboratory’s operations and research budgets with the Department of Energy’s Office of Nuclear Physics.
Physicists develop a universal function that suggests that proton-neutron pairs in the nucleus may explain why quarks inside nuclei have lower average momenta than predicted.
A new study has confirmed that increasing the number of neutrons as compared to protons in the atom’s nucleus also increases the average momentum of its protons.
The determination of the pressure distribution inside the proton is the first measurement of a mechanical property of a subatomic particle. The measurement found that the proton’s building blocks, quarks, are subjected to a pressure of 100 decillion Pascal (1035) near the center of a proton, which is about 10 times greater than the pressure in the heart of a neutron star.
