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…

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…
