Peccei-Quinn NMSSM in the light of 125 GeV Higgs
Kyu Jung Bae, Kiwoon Choi, Eung Jin Chun +3
We study the phenomenology of the Peccei-Quinn invariant extension of the next-to-minimal supersymmetric standard model (NMSSM) in view of the recent discovery of a 125 GeV Higgs b…
Dark radiation and small-scale structure problems with decaying particles
Kiwoon Choi, Ki-Young Choi, Chang Sub Shin
Although the standard ΛCDM model describes the cosmic microwave background radiation and the large scale structure of the Universe with great success, it has some tensions with obs…
The mu-problem and axion in gauge mediation
Kiwoon Choi, Eung Jin Chun, Hyung Do Kim +2
We revisit the idea of generating the Higgs mu parameter through a spontaneously broken Peccei-Quinn (PQ) symmetry in gauge-mediated supersymmetry breaking scenario. For the messen…
Sparticle Spectrum of Large Volume Compactification
Kiwoon Choi, Hans Peter Nilles, Chang Sub Shin +1
We examine the large volume compactification of Type IIB string theory or its F theory limit and the associated supersymmetry breakdown and soft terms. It is crucial to incorporate…
