Approximate degeneracy of heavy-light mesons with the same
Takayuki Matsuki, Qi-Fang Lü, Yubing Dong +1
Careful observation of the experimental spectra of heavy-light mesons tells us that heavy-light mesons with the same angular momentum are almost degenerate. The estimate is giv…
Mixing angle between and in HQET
Takayuki Matsuki, Toshiyuki Morii, Kohichi Seo
Some claim that there are two independent mixing angles (, ) between and states of heavy-light mesons in heavy quark symmetric limit, an…
Derivation of a 1/r^2 potential term for QQ-bar in a potential model
T. Matsuki, X. Liu, T. Morii +1
We clarify the difference among potential models so far proposed to explain mass spectra of heavy-light mesons via transformations of the vacuum. Applying our idea to QQ-bar quarko…
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…
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…
