Axions and other (Super-)WISPs
Markus Ahlers
We present some bottom-up motivations of axions and other weakly interacting sub-eV particles (WISPs) coupling to photons. Typically, these light particles are strongly constrained…
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…
Exotic physics with ultrahigh energy cosmic rays
M. Ahlers, J. I. Illana, M. Masip +1
Ultrahigh energy cosmic rays provide a unique ground for probing new physics. In this talk we review the possibility of testing TeV gravity in interactions of cosmogenic neutrinos…
Long-lived Staus from Cosmic Rays
Markus Ahlers, Jose Ignacio Illana, Manuel Masip +1
The collision of a high energy cosmic ray with a nucleon in the upper atmosphere could produce long-lived heavy particles. Such particles would be very penetrating, since the energ…
On the Particle Interpretation of the PVLAS Data: Neutral versus Charged Particles
Markus Ahlers, Holger Gies, Joerg Jaeckel +1
Recently the PVLAS collaboration reported the observation of a rotation of linearly polarized laser light induced by a transverse magnetic field - a signal being unexpected within…
