Mid-20th-century physics discovered proton resonance, but understanding of the resonating proton’s 3D structure remains limited. Recent experiments at the Jefferson Lab have explored these structures,…
The proton mass radius is smaller than the electric charge radius (a dense core), while a cloud of scalar gluon activity extends beyond the charge…
A new precision measurement of the proton’s electric polarizability has confirmed the presence of an anomaly, raising questions about its origin. Precision measurement of how…
Protons collide with their fellow protons and neutrons with their fellow neutrons more often than predicted. Physicists peer into mirror nuclei. The atomic nucleus is…
Two of tritium’s three nucleons can form short-range correlations that include a proton and one of its neutrons or two neutrons. Credit: DOE’s Jefferson Lab…
New experiments hone in on a never-before-measured region of strong force coupling, a quantity that supports theories accounting for 99 percent of the ordinary mass…
Neutrinos interacting with nuclei. Credit: DOE’s Jefferson Lab Early-career nuclear physicists show that a better understanding of how neutrinos interact with matter is needed to…
A new project will use the electric field in an accelerator cavity to try to levitate a tiny metallic particle, allowing it to store quantum…
A precision measurement of helium and hydrogen mirror isotopes reveals new questions in understanding of nuclear structure. Credit: DOE’s Jefferson Lab A precision measurement of…
In the first direct probes of the core of the nuclear interaction, researchers find that leading theories on interactions between protons and neutrons describe them…
