Exploring CP Violation beyond the Standard Model and the PQ Quality with Electric Dipole Moments
Kiwoon Choi, Sang Hui Im, Krzysztof Jodłowski
In some models of physics beyond the Standard Model (SM), one of the leading low energy consequences of the model appears in the form of the chromo-electric dipole moments (CEDMs)…
Axion dark matter with thermal friction
Kiwoon Choi, Sang Hui Im, Hee Jung Kim +1
Cosmological evolution of axion field in the early universe might be significantly affected by a thermal friction induced by the axion coupling to thermalized hidden sector. We exa…
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…
Potential reconstruction from general power spectrum in single-field inflation
Ki-Young Choi, Jinn-Ouk Gong, Su-beom Kang +1
We suggest a new method to reconstruct, within canonical single-field inflation, the inflaton potential directly from the primordial power spectrum which may deviate significantly…
Precision axion physics with running axion couplings
Kiwoon Choi, Sang Hui Im, Hee Jung Kim +1
We study the renormalization group running of axion couplings while taking into account that the Standard Model can be extended to its supersymmetric extension at a certain energy…
Reconstruction of potentials of the hybrid inflation in the light of primordial black hole formation
Ki-Young Choi, Su-beom Kang, Rathul Nath Raveendran
The large enhancement of the primordial power spectrum of the curvature perturbation can seed the formation of primordial black hole, that can play as a dark matter component in th…
