Andrew J. R. Puckett, Associate Professor, Department of Physics
Professor Puckett is an experimental nuclear/particle physicist studying the internal structure of strongly interacting matter in high-energy fixed-target electron-nucleon and electron-nucleus scattering experiments at Jefferson Lab (JLab). The recently completed 12 GeV upgrade of JLab's Continuous Electron Beam Accelerator Facility to a maximum beam energy of 11 GeV (12 GeV) for electron-beam (photon-beam) experiments, augmented by state-of-the-art target and detector systems, will enable a world-leading physics program leading to three-dimensional imaging of the internal quark structure of protons, neutrons and nuclei with unprecedented precision in both coordinate and momentum space. The ultimate goal of the experiments is to understand how strongly interacting matter is built from its elementary quark and gluon constituents in terms of Quantum Chromodynamics, the theory of the strong interaction.

The Hall A Collaboration at Jefferson Lab is reporting new precision measurements of the cross section for elastic electron-proton scattering at large values of the momentum transfer Q2 and low values of the virtual photon polarization ε. These new data significantly improve the precision of our knowledge of the proton’s magnetic form factor at large […][Read More]
The PREX/PREX-II collaboration is reporting new measurements of the parity-violating asymmetry in elastic electron scattering from the Lead-208 nucleus. This asymmetry, which is generated by the interference between the electromagnetic and weak neutral current interactions between the electron and the nucleus, is highly sensitive to the difference in size between the proton and neutron distributions […][Read More]
The SeaQuest/E906 Collaboration at Fermilab has published new data on measurements of the ratio of anti-down over anti-up quarks in the proton, obtained by studying the Drell-Yan process in collisions of a 120 GeV proton beam from the Fermilab main injector with protons and neutrons in liquid hydrogen and deuterium targets. In the Drell-Yan process, […][Read More]

Does the Hubbard Model have the Right Stuff? *
The Hubbard Model is a minimum model which takes into account the quantum mechanical motion of electrons hopping on a lattice and the local on-site repulsive interaction between them. Proposed by P.W.Anderson, less than a year after the publication of Bednorz's and Muller's discovery, as an appropriate model for the high \(T_c\) cuprates, it has been intensely studied for over three decades. Here we will look at whether it has the "right stuff" and if so, what this implies about the nature of the pairing mechanism.
*"As to just what this ineffable quality was ... well it was like climbing one of those ancient Babylonian pyramids made up of a dizzy progression of steps and ledges, ... and the idea was to prove at every foot of the way up that pyramid ... you had the right stuff". With apologies to T. Wolfe, "The Right Stuff" (1979).
About the speaker: Douglas James Scalapino is an American physicist noted for his contribution to theoretical condensed matter physics. Scalapino was elected as a Member of the National Academy of Sciences in 1991 and to the American Academy of Arts and Sciences in 1992. In 1998 he was awarded the Julius Lilienfeld Prize of the American Physical Society, in 2006 the John Bardeen Prize, and in 2013 the Eugene Feenberg Memorial Medal.

Title: Extraterrestrial Life: Are We the Sharpest Cookies in the Jar?
The search for extraterrestrial life is one of the most exciting frontiers in Astronomy. First tentative clues were identified close to Earth in the form of the weird interstellar object `Oumuamua. Our civilization will mature once we find out who resides on our cosmic street by searching with our best telescopes for unusual electromagnetic flashes, industrial pollution of planetary atmospheres, artificial light or heat, artificial space debris or something completely unexpected. We might be a form of life as primitive and common in the cosmos as ants are in a kitchen. If so, we can learn a lot from others out there through the new frontier of "space archaeology ».
