| Abstract: | The article focuses on an ab initio calculation of the mass difference between neutrons and protons. It states that competition between electromagnetic and mass isospin breaking effects is what responsible for the mass difference. It comments on the use of quantum-electrodynamics computations and lattice quantum-chromodynamics with four nondegenerate Wilson fermion flavors and with an accuracy of 300 kilo-electron volts computed the neutron-proton mass-splitting. |
