4D spin-2 fields from 5D Chern-Simons theory
N. L. González Albornoz, Dieter Lust, S. Salgado +1
We consider a 5-dimensional Chern-Simons gauge theory for the isometry group of Anti-de-Sitter spacetime, , and invoke differe…
Bimetric cosmology is compatible with local tests of gravity
Marvin Lüben, Edvard Mörtsell, Angnis Schmidt-May
Recently, Kenna-Allison et.al. claimed that bimetric gravity cannot give rise to a viable cosmological expansion history while at the same time being compatible with local gravity…
Gravity with antisymmetric components
Chrysoula Markou, Felix J. Rudolph, Angnis Schmidt-May
This work proposes a new gravitational theory formulated in terms of the vierbein field. The vierbein contains components which can be shifted by local Lorentz transformations and…
Ghost-free infinite derivative gravity
Brage Gording, Angnis Schmidt-May
We present the construction of a gravitational action including an infinite series of higher derivative terms. The outcome is a classically consistent completion of a well-studied…
Interactions of multiple spin-2 fields beyond pairwise couplings
S. F. Hassan, Angnis Schmidt-May
Thus far, all known ghost-free interactions of multiple spin-2 fields have involved at most pairwise couplings of the fields, which are direct generalizations of bimetric interacti…
Ghost-free completion of an effective matter coupling in bimetric theory
Marvin Lüben, Angnis Schmidt-May
We consider a particular set of ghost-free interactions for three spin-2 fields in which we freeze out the dynamics of the metric tensor that couples to the matter sector. Integrat…
