Phys. 2014, No. 8, Article ID 083B04, 48 p. (2014). Summary: We investigate a radiative correction to the masses of Kaluza-Klein (KK) modes in a universal extra-dimensional model defined on a six-dimensional spacetime with extra space as a two-sphere orbifold \(S^2/Z_2\). We first define the Feynman rules which are necessary for the calculation. We then calculate the one-loop diagrams which contribute to the radiative corrections to the KK masses, and obtain one-loop corrections to masses for fermions, gauge bosons, and scalar bosons. We estimate the one-loop corrections to KK masses for the first KK modes of standard model particles as a function of momentum cut-off scale, and we determine the lightest KK particle which would be a promising candidate for dark matter.
