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.
