| Abstract: | By allowing the gauge-parameter used to impose the harmonic gauge in M4 × S1 Kaluza-Klein theory with a non-vanishing bare cosmological constant to vary, we show that the physical predictions, such as the effective gauge coupling constant and the radius of the internal dimension, stemming from consideration of the one-loop effective potential, are gauge-dependent. |
