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 ...
We discuss the Cottingham formula and evaluate the proton–neutron electromagnetic mass difference exploiting the state-of-the-art phenomenological input. We decompose individual contributions to the mass splitting into Born, inelastic and subtraction terms. We evaluate the subtraction-function contribution ...
Proton-Neutron Mass Difference in a Unified Gauge Model of Leptons and Hadrons We discuss some problems associated with the physical interpretation and the renormalization of the model devised by Weinberg which combines the SU(2)脳U(1... T Hagiwara,BW Lee - 《Physical Review D》 被引量: 154...
The approach predicts that the neutron-proton mass difference decreases in isospin-symmetric nuclear matter but by a very small amount only.doi:10.1140/epja/i2006-10274-6U. -G. Mei?nerA. M. RakhimovA. WirzbaU. T. YakhshievSocietà Italiana di FisicaThe European Physical Journal A...

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 tests selected for discussion are the finiteness of the neutrino mass in the electron volt region, the decay of protons into antileptons in the range of 1031± 1yr, and the detectability of neutron oscillations at all. The PUT group can also be tested by establishing the existence of ...
