The Discovery Potential of Laser Polarization Experiments
Markus Ahlers, Joerg Jaeckel, Andreas Ringwald
Currently, a number of experiments are searching for vacuum magnetic birefringence and dichroism, i.e. for dispersive and absorptive features in the propagation of polarized light…
Hidden gauginos of an unbroken U(1): Cosmological constraints and phenomenological prospects
A. Ibarra, A. Ringwald, C. Weniger
We study supersymmetric scenarios where the dark matter is the gaugino of an unbroken hidden U(1) which interacts with the visible world only via a small kinetic mixing with the hy…
Probing Hidden Sector Photons through the Higgs Window
Markus Ahlers, Joerg Jaeckel, Javier Redondo +1
We investigate the possibility that a (light) hidden sector extra photon receives its mass via spontaneous symmetry breaking of a hidden sector Higgs boson, the so-called hidden-Hi…
