GOOFy -- a systematic approach
Bohdan Grzadkowski, Odd Magne Ogreid
We investigate in detail a new class (GOOFy) of transformations for bosonic and fermionic fields that leave the Lagrangian density unchanged. The transformations act upon complex s…
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 ,…
Gravitational production of massive vectors non-minimally coupled to gravity
Bohdan Grzadkowski, Anna Socha
A quantum theory of massive Abelian vector bosons with non-minimal couplings to gravity has been studied within an evolving, isotropic, and homogeneous gravitational background. Th…
New Symmetries of the Two-Higgs-Doublet Model
Pedro M. Ferreira, Bohdan Grzadkowski, Odd Magne Ogreid +1
The Two Higgs Doublet Model invariant under the gauge group SU(2)xU(1) is known to have six additional global discrete or continuous symmetries of its scalar sector. We have discov…
Measuring Inflaton Couplings via Primordial Gravitational Waves
Basabendu Barman, Anish Ghoshal, Bohdan Grzadkowski +1
We investigate the reach of future gravitational wave (GW) detectors in probing inflaton couplings with visible sector particles that can either be bosonic or fermionic in nature.…
