A new experiment casts doubt on the leading theory of the nucleus

Researchers at the University of Mainz in Germany have discovered that the current model of nuclear forces is – surprisingly – inadequate. Francesco Pederiva and Petra Riegle-VanGilder, nuclear physicists from the University of Trento, Italy, said the findings showed that physicists “are at a turning point” in terms of understanding atomic nuclei. The current model, which is called chiral effective field theory, is being used to help understand neutron stars, which are being studied as a way of surprising planet formation.
