A high-precision measurement of the photons emitted by neutron decays brings researchers closer to a new test of the standard model. The research, with contributions from UMD Researchers including, Research Scientist and UMD lead  Herbert Breuer, Professor Elizabeth Beise, Alumna Kristin Kiriluk and Adjunct Professors Jeff Nico and Pieter Mumm, was highlighted in APS Physics and is published in Physical Review Letters.
