Under the flat Minkowski space-time background,we give a lowest-order calculation perturbatively of two-point curvature vacuum correlation functions in four-derivative gravity,resulting in that the leading terms of curvature vacuum correlation functions are not zero and the possibility of curvature excitation exists.
结果表明,在四导数引力时空两点间的曲率真空相关函数首项不为零,可能存在曲率激发。
