Jason Chang (iTHEMS/LBNL) and his colleagues have enlisted powerful supercomputers to calculate a quantity known as the "nucleon axial coupling," – which is central to our understanding of a neutron’s lifetime – with an unprecedented precision. Their method offers a clear path to further improvements that may help to resolve the experimental discrepancy of the lifetime of neutrons as well as to learn about as-yet undiscovered physics. The paper was published was published online May 30 in the journal Nature.
