UV stability of 1-loop radiative corrections in higher-derivative scalar field theory

Yugo Abe, Takeo Inami, Keisuke Izumi

We consider the theory of a higher-derivative (HD) real scalar field $\ddot{I}•$ coupled to a complex scalar $\ddot{I}ƒ$, the coupling of the $\ddot{I}•$ and $\ddot{I}ƒ$ being given by two types, $λ_{σϕ}σ…
