基于有效场理论方法计算了矢量暗物质与核子的弹性散射截面。在标准模型中，暗物质被假设为在洛伦兹变换下的矢量粒子，并与包括夸克在内的有色粒子相互作用。在制定散射截面的一般公式后，我们将它们应用到最小普适额外维模型中的第一个卡鲁扎-克莱因光子暗物质的情况。所得的横截面被发现是大于那些在以前的文献中计算。
We evaluate the elastic scattering cross section of vector dark matter with nucleon based on the method of effective field theory. The dark matter is assumed to behave as a vector particle under the Lorentz transformation and to interact with colored particles including quarks in the Standard Model. After formulating general formulae for the scattering cross sections, we apply them to the case of the first Kaluza–Klein photon dark matter in the minimal universal extra dimension model. The resultant cross sections are found to be larger than those calculated in previous literature.
