Is the Z^+(4430) a radially excited state of D_s?
Takayuki Matsuki, Toshiyuki Morii, Kazutaka Sudoh
We present the interpretation that the recently discovered Z^+(4430) by the Belle Collaboration can be a radial excitation of the cs-bar state. We give an explicit cs-bar candidate…
Viable semi-relativistic quark model of heavy-light systems
T. Matsuki, T. Morii, K. Sudoh
The semi-relativistic quark potential model is surprisingly powerful for heavy-light systems if the bound state equation is treated correctly using 1/m_Q expansion with heavy quark…
Structure of Mass Gap between Two Spin Multiplets
Takayuki Matsuki, Toshiyuki Morii, Kazutaka Sudoh
Studying our semirelativistic potential model and the numerical results, which succeeds in predicting and reproducing recently discovered higher resonances of , , , and…
Construction of Lorentz Invariant Amplitudes from Rest Frame Wave Functions in HQET
Takayuki Matsuki, Kohichi Seo
Succeeding in predicting 0^+ and 1^+ states of D and D_s heavy mesons by our semi-relativistic quark potential model, we examine a method how to construct Lorentz-invariant scatter…
Radial Excitations of Heavy Mesons
Takayuki Matsuki, Toshiyuki Morii, Kazutaka Sudoh
Recent discovery of D_s states suggests existence of radial excitations. Our semirelativistic quark potential model succeeds in reproducing these staes within one to two percent of…
