Flavor Violating Axions in the Early Universe
Francesco D'Eramo, Seokhoon Yun
Flavor violating axion couplings can be in action before recombination, and they can fill the early universe with an additional radiation component. Working within a model-independ…
Dark gauge boson production from neutron stars via nucleon-nucleon bremsstrahlung
Chang Sub Shin, Seokhoon Yun
We discuss the dark gauge boson emission from neutron stars via nucleon-nucleon bremsstrahlung. Through the rigorous treatment of the effective field theory prescription and the th…
Thermal QCD Axions across Thresholds
Francesco D'Eramo, Fazlollah Hajkarim, Seokhoon Yun
Thermal axion production in the early universe goes through several mass thresholds, and the resulting rate may change dramatically across them. Focusing on the KSVZ and DFSZ frame…
Thermal axion production at low temperatures: a smooth treatment of the QCD phase transition
Francesco D'Eramo, Fazlollah Hajkarim, Seokhoon Yun
We study thermal axion production around the confinement scale. At higher temperatures, we extend current calculations to account for the masses of heavy quarks, whereas we quantif…
