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…
Phenomenology of a two-component dark matter model
Yeong Gyun Kim, Kang Young Lee, Soo-hyeon Nam
We study a two-component dark matter model consisting of a Dirac fermion and a complex scalar charged under new U(1) gauge group in the hidden sector. The dark fermion plays the do…
Vacuum stability of conformally invariant scalar dark matter models
Yeong Gyun Kim, Kang Young Lee, Jungil Lee +1
We discuss vacuum structure and vacuum stability in classically scale-invariant renormalizable models with a scalar dark matter multiplet of global O(N) symmetry together with an e…
effects to quarks and leptons from flavor unification
Paul H. Frampton, Sin Kyu Kang, Jihn E. Kim +1
In the family grand unification models (fGUTs), we propose that gauge U(1)'s beyond the minimal GUT gauge group are family gauge symmetries. For the symmetry , i.e. $Q_{2}…
Singlet Fermionic Dark Matter with Dark
Dong-Won Jung, Soo-hyeon Nam, Chaehyun Yu +2
We present a fermionic dark matter model mediated by the hidden gauge boson. We assume the QED-like hidden sector which consists of a Dirac fermion and U(1) gauge symmetry, and…
Tetrahedral Symmetry A in Anti-SU(5) GUT
Paul H. Frampton, Jihn E. Kim, Se-Jin Kim +1
We construct a flavor model in an anti-SU(5) GUT with a tetrahedral symmetry . We choose a basis where quarks and charged leptons are already mass eige…
