论文摘要
标量 - 量具有爱因斯坦·希尔伯特（Einstein Hilbert）和非最低互动相互作用，$ \ sim m^2r/2-αϕ^2R/12 $具有Graviton交换引起的接触相互作用。这些总是将理论恢复到不存在$α$的正式爱因斯坦框架中。在爱因斯坦框架中，诱导接触项，然后将其吸收回其他耦合，以定义有效电位（或等效地，重新归一化组）。我们通过计算显示差异的两个帧中的有效势来展示这些效果如何在简单模型中表现出来。
Scalar--tensor theories, with Einstein Hilbert and non-minimal interactions, $\sim M^2R/2 -αϕ^2R/12 $, have graviton exchange induced contact interactions. These always pull the theory back into a formal Einstein frame in which $α$ does not exist. In the Einstein frame, contact terms are induced, that are then absorbed back into other couplings to define the effective potential (or equivalently, the renormalization group). We show how these effects manifest themselves in a simple model by computing the effective potential in both frames displaying the discrepancy.
