额外维度的问题方面
Problematic aspect of extra dimensions
摘要:
我们证明了在多维Kaluza-Klein模型中近日点位移的公式是$Dπm'^2c^2r_g^2/[2(D-2)M^2]$,其中$D$是空间维数的总数.该表达式仅在普通三维$(D=3)$空间中与实验数据吻合较好。这个结果与额外维度的大小无关。因此,考虑多维卡鲁扎-克莱因模型面临着严重的问题。
英文摘要:
We show that in multidimensional Kaluza-Klein models the formula of the perihelion shift is $Dπm'^2c^2r_g^2/[2(D-2)M^2]$ where $D$ is a total number of spatial dimensions. This expression demonstrates good agreement with experimental data only in the case of ordinary three-dimensional $(D=3)$ space. This result does not depend on the size of the extra dimensions. Therefore, considered multidimensional Kaluza-Klein models face a severe problem.
