New Clues to the Proton Puzzle

UVa Physics professor Nilanga Liyanage and his colleagues in the PRad collaboration have made a new measurement of the proton's radius.  Other experiments have arrived at two different, incompatible values for this radius.  The new value derived from PRad data is consistent with the smaller of these values.

Prof. Liyanage described the new work in an invited talk at the 5th Joint Meeting of the APS Division of Nuclear Physics and the Physical Society of Japan, held in Waikoloa, Hawaii this October.  The PRad results are the subject of a story in Science News:


The PRad work was done at Jefferson Lab in Newport News, Virginia.
