Field Redefinition Invariance in Quantum Field Theory
Karyn M. Apfeldorf, Horacio E. Camblong, Carlos R. Ordonez
The issue of field redefinition invariance of path integrals in quantum field theory is reexamined. A ``paradox'' is presented involving the reduction to an effective quantum-mecha…

Renormalization of the Inverse Square Potential
Horacio E. Camblong, Luis N. Epele, Huner Fanchiotti +1
The quantum-mechanical D-dimensional inverse square potential is analyzed using field-theoretic renormalization techniques. A solution is presented for both the bound-state and sca…
