We examine a quantum field theory of two real scalars in which a tree-level relation among the squared-mass parameters of the scalar potential is stable under renormalization group (RG) running despite the absence of a conventional symmetry to explain the stability. By complexifying the original scalar field theory, one can identify the symmetry that guarantees the RG-stability of a...
I will discuss the recently discovered global goofy transformations. Originally, goofy transformations were identified in explicit discussions of the 2HDM, but their understanding is mandatory to describe the renormalization group (RG) fixed point structure of QFTs in general. Even though goofy transformations are explicitly broken by the canonical gauge-kinetic terms, the parameter relations...
Recently, a hitherto unknown class of RG-stable relations between parameters in bosonic field theories have been identified and dubbed as the r0 or ”goofy” symmetries. The 1-loop properties of an invariant 2-Higgs Doublet Model and a minimal symmetric model will be discussed. It is concluded that the symmetry is present at the 1-loop provided the UV cut-off squared transforms non-trivially...
