GOOFy -- a systematic approach
Bohdan Grzadkowski, Odd Magne Ogreid
The paper introduces a new class of GOOFy transformations that keep the Lagrangian invariant, provides a systematic way to build such models, and shows that the resulting parameter…
Imaginary scaling invariance of the one-loop effective potential
P. M. Ferreira, B. Grzadkowski, O. M. Ogreid
Recently, a hitherto unknown class of renormalization group stable relations between parameters of bosonic field theories have been identified and dubbed as the r0 or 'GOOFy' symme…
Power Spectra in Double-Field Inflation Using Renormalization-Group Techniques
Bohdan Grzadkowski, Marco Piva
A perturbative strategy for inflation described by two-inflaton fields is developed using a mathematical analogy with the renormalization-group. Two small quantities, and …
