On the progenitor quark mass matrix
Jihn E. Kim, Se-Jin Kim
We determined the quark mass matrix in terms of a small expansion parameter , which gives correctly all the quark masses and the CKM matrix elements at the elec…
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…
Jarlskog determinant and data on flavor matrices
Jihn E. Kim, Se-Jin Kim, Soonkeon Nam +1
The essences of the weak CP violation, the quark and lepton Jarlskog invariants, are determined toward future model buildings beyond the Standard Model (SM). The equivalence of two…
"Invisible" axion rolling through the QCD phase transition
Jihn E. Kim, Se-Jin Kim
The origin of `invisible' axion in four dimensional effective beyond-standard models from string compactification is discussed and its refined passover through the QCD phase transi…
Flavor mixing inspired by flipped SU(5) GUT
Junu Jeong, Jihn E. Kim, Se-Jin Kim
We obtain a phenomenologically acceptable Cabibbo-Kobayashi-Maskawa matrix in a flipped SU(5) model inspired by the compactification of heterotic string .
Axion energy density, bottle neck period, and ratios between early and late times
Jihn E. Kim, Se-Jin Kim, Soonkeon Nam
The possibility of the "invisible" axion being cold dark matter relies on the acceptable estimates of the current axion energy density. The estimate depends on the nature of QCD ph…
"Invisible" QCD axion rolling through the QCD phase transition
Jihn E. Kim, Se-Jin Kim
Visible matter in the current Universe is a consequence of the phase transition of the strong force, quantum chromodynamics (QCD). This phase transition has occurred at the Univers…
