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…
Determination of f_0(980) Structure by Fragmentation Functions
M. Hirai, S. Kumano, M. Oka +1
We discuss internal structure of an exotic hadron by using fragmentation functions. The fragmentation functions for the f_0(980) meson are obtained by a global analysis of e^++e^-…
Study of Structure of the 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…

Global analysis of hadron-production data in e^+ e^- annihilation for determining fragmentation functions
M. Hirai, S. Kumano, T. -H. Nagai +2
Fragmentation functions of pion, kaon, and nucleon are determined by global analyses of hadron-production data in annihilation. It is particularly important that uncertain…
