One-loop Gauge Couplings in Orbifold Field Theories
Abstract
We discuss the gauge coupling renormalization in orbifold field theories in which the 4-dimensional graviton and/or matter fields are quasi-localized in extra dimension to generate hierarchically different mass scales and/or Yukawa couplings. In such theories, there can be large calculable Kaluza-Klein threshold corrections to low energy gauge couplings, enhanced by the logarithms of small warp factor and/or of small Yukawa couplings. We present the results on those Kaluza-Klein threshold corrections in generic 5-dimensional theory on containing arbitrary 5-dimensional gauge, spinor and scalar fields.
