Kinetic Isocurvature Perturbation

Kyu Jung Bae, Dhong Yeon Cheong, Jinn-Ouk Gong +2

We formulate a new class of primordial perturbations called , where the mass density of dark matter is constant relative to the photon…

Axion-Mediated Inelastic Dark Matter

Kyu Jung Bae, Jongkuk Kim

We consider the axion-mediated scattering processes between dark matter (DM) and nucleus. Substantial contributions are made via the CP-odd gluonic current which induces the spin-d…

The cosmological moduli problem and naturalness

Kyu Jung Bae, Howard Baer, Vernon Barger +1

The cosmological moduli problem (CMP) comes in three parts: 1. potential violation of BBN constraints from late decaying moduli fields, 2. the moduli-induced gravitino problem wher…

PeV Gravitino, Weak-scale Higgsino and GeV Axino in KKLT

Kyu Jung Bae, Kwang Sik Jeong

We realize high scale supersymmetry in the mirage mediation. The Higgs sector is extended with the Peccei-Quinn symmetry, and the higgsino mass term is generated by the Kim-Nilles…

Supersymmetric Clockwork Axion Model and Axino Dark Matter

Kyu Jung Bae, Sang Hui Im

Implications of supersymmetrizing the clockwork axions are studied. Supersymmetry ensures that the saxions and axinos have the same pattern of the coupling hierarchy as the clockwo…

Demystifying Freeze-In Dark Matter at the LHC

Kyu Jung Bae, Myeonghun Park, Mengchao Zhang

Freeze-in mechanism provides robust dark matter production in the early universe. Due to its feeble interactions, freeze-in dark matter leaves signals at colliders which are often…
