Description:

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. The nucleon emerges as a strongly interacting, relativistic bound state of quarks and gluons in Quantum Chromodynamics (QCD), and has a complex internal structure only beginning to be revealed in modern experiments and lattice QCD calculations. 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, which is expected to lead to a new emerging science of nuclear femtography. In this talk, I will demonstrate that as exciting as the nano-science and technology has been, there must be a quantum transition when we enter the era of femto-science and technology. The newly upgraded CEBAF facility at Jefferson Lab and proposed Electron-Ion Collider (EIC) to be built in the US will be a pair of complementary and much needed facilities for exploring the nuclear femtography. They are the most powerful tomographic scanners able to precisely image quarks and gluons inside the proton and nuclei with a sub-femtometer resolution. The new CEBAF and EIC will 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.
