It is shown that using dispersion-theoretical formulas for the electromagnetic self-energies of the nucleons, which involve their electromagnetic form factors, the mass difference between the neutron and the proton can be satisfactorily explained. The expressions for the form factors involved have to ...
The meaning of PROTON is an elementary particle that is identical with the nucleus of the hydrogen atom, that along with the neutron is a constituent of all other atomic nuclei, that carries a positive charge numerically equal to the charge of an electro
The proposed effective Lagrangian incorporates both the medium influence of the surrounding nuclear environment on the single nucleon properties and an explicit isospin-breaking effect in the mesonic sector. The approach predicts that the neutron-proton mass difference decreases in isospin-symmetric ...
The known mass of the proton and neutron are 938 and 940 MeV/C2 respectively. The team has also been able to use the technique to calculate the mass of two mesons and seven heavier baryons. Separating weak from strong While calculating the mass of the proton hardly seems Earth ...

The neutron-proton mass difference is re-evaluated on the basis of new experimental data and knowledge from high-energy electron scattering that the electromagnetic form factors of the proton can no longer be considered as identical. Calculations are performed using second order perturbation in e. ...
