Scientists mix matter and anti-matter to resolve decade-old proton puzzle

Nuclear physicists have used two different methods to measure the proton’s electric form factor. But the deeper that they probe inside the proton, the more the results from these two different methods disagree. Eventually, the measurements provided by one method amount to about five times the quantity yielded by the other. This huge discrepancy is much larger than the experimental uncertainty in the measurements. A new result has allowed researchers to determine the reason behind a large discrepancy in the data between two different methods used to measure the proton’s electric form factor. —> Read More
