Searching for WISPy Cold Dark Matter with a Dish Antenna
Dieter Horns, Joerg Jaeckel, Axel Lindner +3
The cold dark matter of the Universe may be comprised of very light and very weakly interacting particles, so-called WISPs. Two prominent examples are hidden photons and axion-like…
LHC probes the hidden sector
Joerg Jaeckel, Martin Jankowiak, Michael Spannowsky
In this note we establish LHC limits on a variety of benchmark models for hidden sector physics using 2011 and 2012 data. First, we consider a "hidden" U(1) gauge boson under which…
The TeV Dawn of SUSY Models - Consequences for Flavour and CP
Joerg Jaeckel, Valentin V. Khoze
Direct searches and the hints for the Higgs at ~125 GeV put increasing pressure on simple models of SUSY breaking, in particular (but not exclusively) on those that automatically s…
Tunneling of the 3rd Kind: A Test of the Effective Non-locality of Quantum Field Theory
Simon A. Gardiner, Holger Gies, Joerg Jaeckel +1
Integrating out virtual quantum fluctuations in an originally local quantum field theory results in an effective theory which is non-local. In this Letter we argue that tunneling o…
WISPy Cold Dark Matter
Paola Arias, Davide Cadamuro, Mark Goodsell +3
Very weakly interacting slim particles (WISPs), such as axion-like particles (ALPs) or hidden photons (HPs), may be non-thermally produced via the misalignment mechanism in the ear…
