Effective Field Theory and High-Precision Calculations of Nuclear Electroweak Processes

High-precision calculations of electroweak processes in light nuclei are of great importance for multiple reasons. Gerry Brown together with Dan-Olof Riska published in 1972 a famous calculation on radiative capture of a thermal neutron on a proton, and their work was a precursor of subsequent great developments in high-precision calculations of electroweak processes in light nuclei. The application of effective field theory to nuclear systems is a prominent example of these developments. We present an overview of it with main emphasis placed on those topics in which we ourselves have been involved.
