ALPINIST: Axion-Like Particles In Numerous Interactions Simulated and Tabulated
Jan Jerhot, Babette Döbrich, Fatih Ertas +2
Proton beam dump experiments are among the most promising strategies to search for light and feebly interacting states such as axion-like particles (ALPs). The interpretation of th…
Turn up the volume: Listening to phase transitions in hot dark sectors
Fatih Ertas, Felix Kahlhoefer, Carlo Tasillo
Stochastic gravitational wave (GW) backgrounds from first-order phase transitions are an exciting target for future GW observatories and may enable us to study dark sectors with ve…
Leading Logs in QCD Axion Effective Field Theory
Gonzalo Alonso-Álvarez, Fatih Ertas, Joerg Jaeckel +2
The axion is much lighter than all other degrees of freedom introduced by the Peccei-Quinn mechanism to solve the strong CP problem. It is therefore natural to use an effective fie…
Hidden Photon Dark Matter in the Light of XENON1T and Stellar Cooling
Gonzalo Alonso-Álvarez, Fatih Ertas, Joerg Jaeckel +2
The low-energy electronic recoil spectrum in XENON1T provides an intriguing hint for potential new physics. At the same time, observations of horizontal branch stars favor the exis…
On the interplay between astrophysical and laboratory probes of MeV-scale axion-like particles
Fatih Ertas, Felix Kahlhoefer
Studies of axion-like particles (ALPs) commonly focus on a single type of interaction, for example couplings only to photons. Most ALP models however predict correlations between d…
Loop-induced direct detection signatures from CP-violating scalar mediators
Fatih Ertas, Felix Kahlhoefer
We investigate direct detection signatures of dark matter particles interacting with quarks via a light spin-0 mediator with general CP phases. Since tree-level scattering may be s…
Model-independent bounds on light pseudoscalars from rare B-meson decays
Babette Döbrich, Fatih Ertas, Felix Kahlhoefer +1
New light pseudoscalars, such as axion-like particles, appear in many well-motivated extensions of the Standard Model and provide an exciting target for present and future experime…
