Form Factors in D Meson Decays

Dae Sung Hwang, Do-Won Kim

We study the $d Γ/ d q^{2}$ spectra and the branching fractions of the $D$ meson exclusive semileptonic decays with the lepton mass effects into consideration. We investigate their sen…

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…

Fermi motion parameter $p_{F}$ of $B$ meson from relativistic quark model

Daesung Hwang, C. S. Kim, Wuk Namgung

The Fermi motion parameter $p_{_{F}}$ is the most important parameter of ACCMM model, and the value $p_{_{F}} \sim 0.3$ GeV has been used without clear theoretical or experimental evid…
