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…
Axion emission from supernova with axion-pion-nucleon contact interaction
Kiwoon Choi, Hee Jung Kim, Hyeonseok Seong +1
We examine the axion emission from supernovae with a complete set of relevant axion couplings including the axion-pion-nucleon contact interaction which was ignored in the previous…
Aligned Natural Inflation in the Large Volume Scenario
Stephen Angus, Kang-Sin Choi, Chang Sub Shin
We embed natural inflation in an explict string theory model and derive observables in cosmology. We achieve this by compactifying the type IIB string on a Calabi-Yau orientifold,…
Massless Preheating and Electroweak Vacuum Metastability
Jeff Kost, Chang Sub Shin, Takahiro Terada
Current measurements of Standard Model parameters suggest that the electroweak vacuum is metastable. This metastability has important cosmological implications, because large fluct…
