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…
Crossed products of operator systems
Samuel J. Harris, Se-Jin Kim
In this paper we introduce the crossed product construction for a discrete group action on an operator system. In analogy to the work of E. Katsoulis and C. Ramsey, we describe thr…
