Factorization and Decay Constants and
D. S. Hwang, Y. -Y. Keum
We calculate the decay constants of and with $\bar{B}^0 \ra D^{+}\ell^{-}ν$ and $\bar{B}^0 \ra D^{+}D_s^{-(*)}$ decays. In our analysis we take the factorization me…
Model Independent Calculation of
Dae Sung Hwang, Do-Won Kim
Using the formulas for the distribution with non-zero lepton mass and experimentally determined form factors, we calculate the spectra a…
Particle dynamics in a class of 2-dimensional gravity theories
Dae Sung Hwang, Youngjai Kiem, Dahl Park
We provide a method to determine the motion of a classical massive particle in a background geometry of 2-dimensional gravity theories, for which the Birkhoff theorem holds. In par…
Ratios of and Meson Decay Constants in Relativistic Quark Model
Dae Sung Hwang, Gwang-Hee Kim
We calculate the ratios of and meson decay constants by applying the variational method to the relativistic hamiltonian of the heavy meson. We adopt the Gaussian and hydrog…
Decay Constants and Semileptonic Decays of Heavy Mesons in Relativistic Quark Model
Dae Sung Hwang, C. S. Kim, Wuk Namgung
We investigate the and mesons in the relativistic quark model by applying the variational method with the Gaussian wave function. We calculate the Fermi momentum parameter…
Fermi motion parameter of meson from relativistic quark model
D. S. Hwang, C. S. Kim, W. Namgung
The Fermi motion parameter is the most important parameter of ACCMM model, and the value GeV has been used without clear theoretical or experimental evid…
