Nuclear Potential with Two Pion Exchange
Takehisa Fujita, Naohiro Kanda, Sachiko Oshima
We carefully calculate the nucleon-nucleon interaction due to two pion exchange processes by properly evaluating the corresponding Feynman diagrams. In the estimation, we have made…
Electric Dipole Moments of Neutron-Odd Nuclei
Takehisa Fujita, Sachiko Oshima
The electric dipole moments (EDMs) of neutron-odd nuclei with even protons are systematically evaluated. We first derive the relation between the EDM and the magnetic moment operat…
A New Relation between Lamb Shift Energies
Hiroaki Kubo, Takehisa Fujita, Naohiro Kanda +4
We derive a new relation between the observed Lamb shift energies of hydrogen and muonium atoms. The relation is based on the non-relativistic description of the Lamb shift, and th…
New Renormalization Scheme of Vacuum Polarization in QED
T. Fujita, N. Kanda, H. Kato +4
We examine the vacuum polarization contribution in the renormalization scheme of QED. Normally, the quadratic divergence term is discarded under the condition that the counter term…
Unphysical Gauge Fixing in Higgs Mechanism
T. Fujita, A. Kusaka, K. Tsuda +1
The unitary gauge in the Higgs mechanism is to impose the condition of on the Higgs fields. However, this is not the gauge fixing but simply a procedure for producin…
Mistery of Real Scalar Klein-Gordon Field
T. Fujita, S. Kanamaki, A. Kusaka +1
The mystery that the real scalar Klein-Gordon field has vanishing current densities is resolved. The scalar field is shown to be a complex field due to the condition of possessing…
