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…
