Reopen parameter regions in two-Higgs doublet models

The stability of the electroweak potential is a very important constraint for models of Wall Decor new physics.At the moment, it is standard for Two-Higgs doublet models (THDM), singlet or triplet extensions of the standard model to perform these checks at tree-level.However, these models are often studied in the presence of very large couplings.Th

Rotating kinky braneworlds

Abstract Cylindrical braneworlds have been used in the literature as a convenient way to resolve co-dimension-two branes.They are prevented from collapsing by a massless worldvolume field with non-trivial winding, but here we discuss another way of preventing collapse, which is to rotate the brane.We use a simple microscopic field theory model of a
