Gravitational Vector Dark Matter
Christian Gross, Sotirios Karamitsos, Giacomo Landini +1
A new dark sector consisting of a pure non-abelian gauge theory has no renormalizable interaction with SM particles, and can thereby realise gravitational Dark Matter (DM). Gauge i…
Frame Covariant Nonminimal Multifield Inflation
Sotirios Karamitsos, Apostolos Pilaftsis
We introduce a frame-covariant formalism for inflation of scalar-curvature theories by adopting a differential geometric approach which treats the scalar fields as coordinates livi…
Frame-Covariant Formulation of Inflation in Scalar-Curvature Theories
Daniel Burns, Sotirios Karamitsos, Apostolos Pilaftsis
We develop a frame-covariant formulation of inflation in the slow-roll approximation by generalizing the inflationary attractor solution for scalar-curvature theories. Our formulat…
