Symmetric tensor portals to dark matter I: Creation of dark scalars
Brian Dignean, Alexander J. Magnus, Rainer Dick
We examine the creation of scalar dark matter through a symmetric tensor portal. We find that both freeze-in and thermal freeze-out through a symmetric tensor mediator can create s…

Antisymmetric tensor portals to dark matter
Alexander J. Magnus, Joshua G. Fenwick, Rainer Dick
Both freeze-in of very weakly coupled dark matter and freeze-out of initially thermalized dark matter from the primordial heat bath provide interesting possibilities for dark matte…
