Astrophobic Axions.

Summary of "Astrophobic Axions."

We propose a class of axion models with generation-dependent Peccei-Quinn charges for the known fermions that allow one to suppress the axion couplings to nucleons and electrons. Astrophysical limits are thus relaxed, allowing for axion masses up to O(0.1)  eV. The axion-photon coupling remains instead sizable, so that next-generation helioscopes will be able to probe this scenario. Astrophobia unavoidably implies flavor-violating axion couplings so that experimental limits on flavor-violating processes can provide complementary probes. The astrophobic axion can be a viable dark matter candidate in the heavy mass window and can also account for anomalous energy loss in stars.

Axion-Plasmon Polaritons in Strongly Magnetized Plasmas.

Axions are hypothetical particles related to the violation of the charge-parity symmetry within the strong sector of the standard model, being one of the most prone candidates for dark matter. Multipl...

Axion-Driven Cosmic Magnetogenesis during the QCD Crossover.

We propose a mechanism for the generation of a magnetic field in the early Universe during the QCD crossover assuming that dark matter is made of axions. Thermoelectric fields arise at pressure gradie...

Solving the Hierarchy Problem Discretely.

We present a new solution to the hierarchy problem utilizing nonlinearly realized discrete symmetries. The cancellations occur due to a discrete symmetry that is realized as a shift symmetry on the sc...

QCD Axion Dark Matter with a Small Decay Constant.

The QCD axion is a good dark matter candidate. The observed dark matter abundance can arise from misalignment or defect mechanisms, which generically require an axion decay constant f_{a}∼O(10^{11})...
