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…
