A light scalar WIMP through the Higgs portal?
Michel H. G. Tytgat
In these proceedings, I report on the status of a simple singlet scalar dark matter model in the light of recent results from both direct detection experiments, in particular DAMA,…
Status of sub-GeV Hidden Particle Searches
Sarah Andreas, Andreas Ringwald
Hidden sector particles with sub-GeV masses like hidden U(1) gauge bosons, the NMSSM CP-odd Higgs, and other axion-like particles are experimentally little constrained as they inte…
Constraints on a very light CP-odd Higgs of the NMSSM and other axion-like particles
Sarah Andreas, Oleg Lebedev, Saul Ramos-Sanchez +1
In the NMSSM, a light CP-odd Higgs arises due to spontaneous breaking of approximate symmetries such as Peccei-Quinn or R-symmetry and is motivated by string theory. The case when…
A light scalar WIMP through the Higgs portal and CoGeNT
Sarah Andreas, Chiara Arina, Thomas Hambye +2
If dark matter (DM) simply consists in a scalar particle interacting dominantly with the Higgs boson, the ratio of its annihilation cross section ---which is relevant both for the…
