Bounds on Very Weakly Interacting Sub-eV Particles (WISPs) from Cosmology and Astrophysics
Javier Redondo
Many weakly interacting sub-electronVolt particles (WISPs) are easily accommodated in extensions of the standard model. Generally the strongest bounds on their existence come from…
Can the PVLAS particle be compatible with the astrophysical bounds?
Javier Redondo
The PVLAS collaboration has announced recently the observation dichroism and birefringence of vacuum permeated by a intense magnetic field. Both are typical predictions of the exis…
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…
The low energy frontier: probes with photons
Javier Redondo
I discuss different aspects of the phenomenology of hypothetical sub eV mass particles arising in the context of extensions of the standard model. I focus on a simple extension bas…
Helioscope Bounds on Hidden Sector Photons
Javier Redondo
The flux of hypothetical "hidden photons" from the Sun is computed under the assumption that they interact with normal matter only through kinetic mixing with the ordinary standard…
Light scalars coupled to photons and non-newtonian forces
Arnaud Dupays, Eduard Masso', Javier Redondo +1
A particle coupling to two photons couples also to charged particles, like protons, through a loop. If the particle is a light scalar this induced coupling to protons leads to…
