Constraints on Axion Models
Mark Hindmarsh, Photis Moulatsiotis
Two particular classes of axion models are presented, each one yielding a lower bound on the axion decay constant, based though on different considerations. In the first class only…

Constraints on Axion Models from
Mark Hindmarsh, Photis Moulatsiotis
We explore a new class of axion models in which some, but not all, of the left-handed quarks have a Peccei-Quinn symmetry. These models are potentially afflicted by flavour changin…

Constraints on Variant Axion Models
Mark Hindmarsh, Photis Moulatsiotis
A particular class of variant axion models with two higgs doublets and a singlet is studied. In these models the axion couples either to the -quark or -quark or both, but not…
