Removing Ostrogradsky modes in multi-field higher-order scalar-tensor theories
Hamed Bouzari Nezhad
We study multi-field higher-order scalar-tensor theories and examine how the unwanted Ostrogradsky modes can be removed. For a general class of theories with an arbitrary number $\…

Degenerate higher-order scalar-tensor theories in metric-affine gravity
Hamed Bouzari Nezhad
We construct the metric-affine analogue of the quadratic degenerate higher-order scalar-tensor (DHOST) theories. We begin with the metric-affine completion of the quadratic DHOST s…

Scalar fields with derivative coupling to curvature in the Palatini and the metric formulation
Hamed Bouzari Nezhad, Syksy Rasanen
We study models where a scalar field has derivative and non-derivative couplings to the Ricci tensor and the co-Ricci tensor with a view to inflation. We consider both the metric f…
