Axion Dark Matter from Heavy Quarks
Mohammad Aghaie, Giovanni Armando, Angela Conaci +5
We propose simple scenarios where the observed dark matter abundance arises from decays and scatterings of heavy quarks through freeze-in of an axion-like particle with mass in the…

A Leptonic ALP Portal to the Dark Sector
Giovanni Armando, Paolo Panci, Joachim Weiss +1
We discuss the leptonic ALP portal as a simple scenario that connects observed discrepancies in anomalous magnetic moments to the Dark Matter relic abundance. In this framework an…

Bounds on Ultralight Dark Matter from NANOGrav
Mohammad Aghaie, Giovanni Armando, Alessandro Dondarini +1
The compelling evidence for the detection of the stochastic gravitational wave background by NANOGrav imposes constraints on the mass of compact cores of ultralight dark matter, al…
