Proton radius mystery deepens as deuterium measurement comes up short. Krzysztof Pachucki, a theoretical physicist at the University of Warsaw in Poland, says that the Jefferson Lab result “makes the small value of the proton radius the more likely to be the

 right one”.However, he says the case is not closed yet, pointing out that a group in Paris measuring the 1S-3S transition in hydrogen ...</div>
