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…
New Concept of First Quantization
T. Fujita, S. Kanemaki, S. Oshima
We derive a Lagrangian density of Dirac field by employing the local gauge invariance and the Maxwell equation as the fundamental principle. The only assumption made here is that t…
Off-Shell Formulation of Supergravity on Orbifold
Tomoyuki Fujita, Taichiro Kugo, Keisuke Ohashi
An off-shell formulation is given for the ``supersymmetry in singular spaces'' which has recently been developed in an on-shell formalism by Bergshoeff, Kallosh and Van Proeyen usi…
Superconformal Tensor Calculus in Five Dimensions
Tomoyuki Fujita, Keisuke Ohashi
We present a full superconformal tensor calculus in five spacetime dimensions in which the Weyl multiplet has 32 Bose plus 32 Fermi degrees of freedom. It is derived by the dimensi…
