Testing Antimatter Couplings with Spectroscopy
Joerg Jaeckel, Lucas Puetter
We investigate how scalar-mediated potentials with Lorentz-violating couplings to Standard Model fermions affect spectroscopic observables in atoms and highly charged ions. Suitabl…
Stochastic Tsunamis: Diffuse Scalar Background from Black Hole Formation
Arturo de Giorgi, Joerg Jaeckel
The authors suggest that the abrupt disappearance of a static scalar field when massive stars collapse into black holes generates bursts of scalar radiation, which accumulate over…
Constraining Multiple Kinetically Mixed Dark Photons
Joerg Jaeckel, Sebastian Monath
Extra U(1) gauge bosons under which Standard Model particles are uncharged, aka dark photons, are a simple and well-motivated extension of the Standard Model. There could be a sing…
The String Theory Photoverse
Thibaut Coudarchet, Arthur Hebecker, Joerg Jaeckel +1
String theory compactifications come with numerous factors, implying the presence of many hidden photons in the low-energy EFT. One may call this the ``string photoverse''.…
Scalar Tsunamis from Black Hole Formation
Arturo de Giorgi, Yeray Garcia del Castillo, Joerg Jaeckel
Stars and other macroscopic objects may be surrounded by potentially large field configurations of very light scalars coupled to ordinary matter. If the star ends in a black hole,…
Multiple Axions in Laboratory Experiments
Arturo de Giorgi, Joerg Jaeckel, Sebastian Monath +1
Axions and axion-like particles generically appear in extensions of the Standard Model. While many searches assume only a single axion species, there may exist a whole spectrum of…
