Accelerated cosmological expansion from pseudo-Hermiticity
Edmund J. Copeland, Andrei Lazanu, Peter Millington +1
We show that a well-studied pseudo-Hermitian field theory composed of two complex scalar fields can generate accelerated cosmological expansion through a novel mechanism. The dynam…
Recasting scalar-tensor theories of gravity for colliders
Andrei Lazanu, Peter Millington, Sergio Sevillano Muñoz
Diagrammatic approaches to perturbation theory transformed the practicability of calculations in particle physics. In the case of extended theories of gravity, however, obtaining t…
Scalar radiation zeros at the LHC
Christoph Englert, Andrei Lazanu, Peter Millington
We consider a class of singlet scalar extensions of the Standard Model of particle physics in which the scalar couples only to off-shell states. As a result, low-order tree-level p…
Recent Developments in Degenerate Higher Order Scalar Tensor Theories
Andrei Lazanu
Degenerate Higher Order Scalar Tensor (DHOST) theories are the most general scalar-tensor theories whose Lagrangian depends on the metric tensor and a single scalar field and its d…
