Simona Malace, a staff scientist at Jefferson Lab, likes to refer to protons and neutrons as “tiny laboratories” that enable her studies of the heart of matter. For decades, physicists like Malace have probed protons and neutrons, particles known collectively as nucleons, to study the strong interaction. The strong interaction holds most ordinary matter together: it binds protons and neutrons to form the atomic nucleus, and smaller particles called quarks to form nucleons themselves. It’s one of the four fundamental interactions. “The universe we are moving in is governed by these interactions,” says Malace. “So knowing about them is like knowing about the world around you.”

Much like two friendly neighbors getting together to chat over a cup of coffee, the minuscule particles in our sub-atomic world also come together to engage in a kind of conversation. Now, nuclear scientists are developing tools to allow them to listen in on the particles’ gab fests and learn more about how they stick together to build our visible universe.
Jozef Dudek is a staff scientist at the U.S. Department of Energy’s Jefferson Lab and an assistant professor of physics at the College of William & Mary. He and his colleagues recently carried out the first complex calculations of a particle called the sigma and published the result in Physical Review Letters in January.

Diamonds are one of the most coveted gemstones. But while some may want the perfect diamond for its sparkle, physicists covet the right diamonds to perfect their experiments. The gem is a key component in a novel system that enables precision measurements that could lead to the discovery of new physics in the sub-atomic realm — the domain of the particles and forces that build the nucleus of the atom.
Explorations of this realm require unique probes with just the right characteristics, such as the electrons that are prepared for experiments inside the Continuous Electron Beam Accelerator Facility at Jefferson Lab.

Optical fiber networks carry the lifeblood of research facilities like Jefferson Lab. Bundles of these thin glass, fiber or plastic lines transmit vast amounts of information and data, coded into beams of light and traveling nearly as quickly.
The lab’s original optical fiber network, installed in the late 1980s and early 1990s, was built to transmit data from CEBAF’s (then) three experimental halls and for high-speed Internet connectivity. Over the years, many of the lab’s infrastructure and utilities systems were also moved onto the fiber optic network; and it now carries operational data for everything from telecommunications and email to security and heating, ventilation and cooling.

CERN, the European Organization for Nuclear Research, has announced that its LHCb experiment has discovered two possible pentaquark particles that haven't been seen before. If confirmed, these new particles will herald the discovery of a whole new class of particles.
Pentaquarks gained international attention in 2003, when evidence for a lighter cousin of the pentaquarks announced by CERN was thought to have been found by experimenters at SPring-8 in Japan, the Department of Energy's Thomas Jefferson National Accelerator Facility, the Alikhanov Institute for Theoretical and Experimental Physics (ITEP) in the Russian Federation and the ELectron Stretcher and Accelerator (ELSA) in Germany.

Fans of science and science fiction have been warned that mixing matter with anti-matter can yield explosive results. And that’s just what physicists were counting on, in hopes of blowing wide open a puzzle that has confounded them for the last decade.
The puzzle comes from experiments that aimed to determine how quarks, the building blocks of the proton, are arranged inside that particle. That information is locked inside a quantity that scientists refer to as the proton’s electric form factor. The electric form factor describes the spatial distribution of the quarks inside the proton by mapping the charge that the quarks carry.

For as long as Matthew Burton can remember, he has been into science. When asked how far back, he readily recalls trying to bend a laser with magnets for an elementary school science fair project.
The young researcher has always been excited by technology, and physics, he says, gave him a path into that.
After high school, he headed to James Madison University on a (science, technology, engineering and math) STEM scholarship to study fundamental physics, and then to The College of William and Mary for its Ph.D. physics program.
