本文研究了在一个普遍的额外维模型中Kaluza-Klein（KK）模质量的辐射修正，该模型定义在一个额外空间为两球轨道的六维时空上。我们首先定义计算所需的费曼规则。然后，我们计算的单圈图，有助于辐射修正的KK质量，并获得单圈修正的费米子，规范玻色子，标量玻色子的质量。我们估计的单圈修正KK质量的第一KK模式的标准模型粒子的动量截止尺度的函数，我们确定最轻的KK粒子，这将是一个有前途的候选人的暗物质。
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. 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.
