Noncritical Conformal Gravity and Four-Dimensional Liouville Theory
Hikaru Kawai, Nobuyoshi Ohta
We study the quantum aspects of the conformal gravity in four dimensions, specifically addressing a known discrepancy in beta functions between general quadratic curvature theories…
Essential Renormalization Group Equation for Gravity coupled to a Scalar field
Nobuyoshi Ohta, Masatoshi Yamada
We study the essential renormalization group equation, in which inessential couplings are removed via field redefinitions, for Einstein gravity coupled to a massive scalar field in…
Standard Running, "Physical Running", Cosmological Constant and Newton Coupling
Hikaru Kawai, Nobuyoshi Ohta
Recently it is asserted that the standard beta function does not describe the correct running of the coupling constant in some theories. We show that the problem arises from the as…
Wave Function Renormalization in Asymptotically Safe Quantum Gravity
Hikaru Kawai, Nobuyoshi Ohta
We discuss the effect of wave function renormalization (WFR) in asymptotically safe gravity. We show that there are two WFR-invariant quantities, and the renormalization (RG) equat…
An Observation on the Beta Functions in Quadratic Gravity
Hikaru Kawai, Nobuyoshi Ohta
We study the beta functions for the dimensionless couplings in quadratic curvature gravity, and find that there is a simple argument to restrict the possible form of the beta funct…
