Quintessential Axions
Jihn E. Kim
I review the dark energy solutions by a very light pseudoscalar called "quintessential axion". For the explicit breaking terms, we consider both the global anomaly U(1)$_{\rm globa…
Quintessential Axions from a New Confining Force
Jihn E. Kim, Younggeun Kim, Soonkeon Nam
Almost massless mesons created at the condensation scale of extra nonabelian gauge group can be candidates of dark energy source. This can be another motivation for introducing an…
Probing Neutrino Dipole Portal at COHERENT Experiment
Jihn E. Kim, Arnab Dasgupta, Sin Kyu Kang
Motivated by the first observation of coherent-elastic neutrino-nucleus scattering at the COHERENT experiment, we confront the neutrino dipole portal giving rise to the transition…
Electromagnetic properties of neutrinos from scattering on bound electrons in atom
Junu Jeong, Jihn E. Kim, Sungwoo Youn
We consider the effects of bound atomic electrons scattered by solar neutrinos due to the electromagnetic properties of neutrinos. This necessiate considering the recoil of atomic…
R-parity from string compactification
Jihn E. Kim
The strategy for assigning parity in the string compactification is presented. For the visible sector, an anti-SU(5) (flipped-SU(5)) grand unification (GUT) model with thr…
Ultralight Axions Versus Primordial Black Holes
Claudio Corianò, PaulH. Frampton, Jihn E. Kim
We reconsider entropy arguments which have been previously argued to support the idea that the dark matter constituents are primordial black holes with many solar masses. It has re…
