Abstract: The proton and neutron, known as nucleons, are the fundamental building blocks of all atomic nuclei and make up essentially all the visible matter in the universe, including the stars, the planets, and us. Nucleons are not static but have complex internal structure, emerged as strongly interacting and relativistic bound states of quarks and gluons of Quantum Chromodynamics. Both theory and experimental technology have now reached a point where human is capable of exploring the inner structure of nucleons and nuclei at sub-femtometer distance, leading to a new emerging science of nuclear femtography. In this talk, I will demonstrate that the newly upgraded CEBAF facility at Jefferson Lab and proposed Electron-Ion Collider to be built in the US will be a pair of complementary and necessary facilities for exploring the science of nuclear femtography. They are the most powerful tomographic scanners and/or microscopes able to precisely image inner structure of nucleon and nuclei with a sub-femtometer resolution to help address the most compelling unanswered questions about the elementary building blocks of the visible world, and are capable of taking us to the next frontier of the Standard Model of physics.
Short Bio: At the Jefferson lab, Dr. Jianwei Qiu oversees a broad program of theoretical research in support of the physics studied by the Continuous Electron Beam Accelerator Facility (CEBAF) experimental program. Prior to joining Jefferson Lab in October 2016, Dr. Qiu had been a senior physicist and the Nuclear Theory Group Leader at Brookhaven National Lab, and a Brookhaven Professor at Stony Brook University in Stony Brook, New York. Dr. Qiu received his Ph.D. in theoretical physics in 1987 from Columbia University in New York City, and was a postdoctoral research associate at Argonne National Lab and at the C.N. Yang Institute for Theoretical Physics at Stony Brook University. In 1991, Dr. Qiu joined the faculty of the Department of Physics and Astronomy at Iowa State University in Ames, where he held positions as an assistant, associate and full professor of physics and astronomy. He moved to Brookhaven National Lab/Stony Brook University in 2010.
His research focus is in Quantum Chromodynamics (QCD) and its applications in high-energy particle and nuclear physics, in particular, in theoretical and phenomenological study of the strong force.
