The proton is the only composite building block of matter that is stable in nature, making its properties key to understanding the formation of matter. A team of physicists measured the proton’s electric polarizability, which characterizes the proton’s susceptibility to deformation, or its “stretchability,” in the presence of a photon’s electromagnetic field. The results reveal a puzzling new structure – a bump in the polarizability that nuclear theory cannot explain.

Heavy ion collisions using gold nuclei found a phase of nuclear matter with freely moving quarks and gluons, the Quark Gluon Plasma (QGP). Scientists are aiming to establish if a critical point exists in the phase diagram of nuclear matter, where the QGP would coexist with a gas of protons, neutrons, and other particles. Research at the Relativistic Heavy Ion Collider indicates that if this critical point exists, it is between energies of 3 and 20 giga-electron volts.

Quarks are distributed differently in free protons and neutrons versus those inside nuclei, something called “the EMC effect.” Scientists previously thought that the EMC effect treated the up and down quarks in protons and neutrons equally. New high-precision data from the MARATHON experiment indicates that the EMC effect may exert more influence on the distribution of down quarks compared to up quarks inside nuclei.

Physicists Confirm Hitch in Proton Structure
Thomas Jefferson National Accelerator Facility

A new precision measurement of the proton’s electric polarizability performed at Jefferson Lab has confirmed an unexplained bump in the data. The proton’s electric polarizability shows how susceptible the proton is to deformation, or stretching, in an electric field. Like size or charge, the electric polarizability is a fundamental property of proton structure. The data bump was widely thought to be a fluke when seen in earlier measurements, so this new, more precise measurement confirms the presence of the anomaly and signals that an unknown facet of the strong force may be at work. The research has just been published in the journal Nature.
