Relativistic Hubble's law
Yongkyu Ko
Considering the hyperbolic nature of the universe, the Hubble's law and the inverse square laws such as, the Coulomb's law and Newton's gravitational law, should be modified in acc…
Hyperbolic triangle in the special theory of relativity
Yongkyu Ko
The vector form of a Lorentz transformation which is separated with time and space parts is studied. It is necessary to introduce a new definition of the relative velocity in this…
The charge radii and the decay rates of the pseudoscalar meson
Yongkyu Ko
The charge radii and the decay rates of the pion and kaons are calculated, using the relativistic equation of motion with a linear potential. Those physical quantities are quite we…
Derivation of a Quark Confinement Potential from QCD
Yongkyu Ko
A quark confinement potential is derived from QCD Lagrangial under the two assumptions in the energy region relevant to quark confinement. The possibility of perturbation in QCD is…
