Decay Constant Ratios $f_{η_{c}} / f_{J / ψ}$ and $f_{η_{b}} / f_{Υ}$

Dae Sung Hwang, Gwang-Hee Kim

We calculate the decay constant ratios $f_{η_{c}} / f_{J / ψ}$ and $f_{η_{b}} / f_{Υ}$ . In the calculation we take into account the mock meson structures of the mesons, as well as the differen…

Solving the Puzzle of $\frac{M _{D^{}} - M _{D}}{M _{D_{s}^{}} - M _{D_{s}}}$ $≃$ $\frac{M _{B^{}} - M _{B}}{M _{B_{s}^{}} - M _{B_{s}}}$ $≃$ $1$

Dae Sung Hwang, Gwang-Hee Kim

The commonly used Hamiltonian of the chromomagnetic hyperfine splitting is inversely proportional to the product of the masses of two constituent quarks composing the meson. So it…

Magnetic Field Dependence of Macroscopic Quantum Tunneling and Coherence of Ferromagnetic Particle

Gwang-Hee Kim, Dae Sung Hwang

We calculate the quantum tunneling rate of a ferromagnetic particle of $\sim 100 A ˚$ diameter in a magnetic field of arbitrary angle. We consider the magnetocrystalline anisotropy w…
