Probing light axion-like particles in vector boson fusion at CMS with data parking and scouting
Sena Durgut, Mariel Peczak, Gonzalo Alonso-Álvarez +4
Axion-like particles (ALPs) with masses between 10 MeV and 10 GeV and moderately small couplings sit in an experimental blind spot. They decay too fast for intensity-frontier exper…
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
Massive astrophysical objects can source huge static configurations of a scalar field. When such an object ends up forming a black hole, for instance, via a core-collapse supernova…
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…
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…
