Challenging the Dominant Theory: New Experiment Questions Nucleus Understanding
A recent experiment measuring the strong nuclear force in helium-4 nuclei has revealed a significant discrepancy between theoretical predictions and experimental results. The swelling of the helium nuclei, which is a magnification of deficiencies in theoretical calculations, was found to be twice as large as expected. This challenges the current leading theory of nuclear interactions, known as chiral effective field theory, and highlights the need for a better understanding of even the simplest nuclear systems. Further research is needed to determine the cause of this discrepancy and to improve our understanding of the strong nuclear force.
