Exploring Neutron Decay Interaction through Right-Handed Currents in the Universe

Nuclear theorists have discovered a new effect in neutron decay related to the interplay of weak and electromagnetic forces, which alters our understanding of neutron decay and signals the need for high-precision computations of electromagnetic effects. This research affects the search for new interactions, technically known as “right-handed currents,” that restore the universe’s mirror-reflection symmetry. The calculation was performed with a modern method, known as “effective field theory,” which efficiently organizes the importance of fundamental interactions in phenomena involving strongly interacting particles.
