Review and interpretation of the new heavy states discovered at the $B$ -factories

Marina Nielsen

I discuss some recent discoveries in the spectroscopy of the charmonium-like resonances, and some of their theoretical interpretations are reviewed.

Can the $π^{+} χ_{c 1}$ resonance structures be $D^{} D ˉ^{}$ and $D_{1} D ˉ$ molecules?

Su Houng Lee, Kenji Morita, Marina Nielsen

We use QCD sum rules to study the recently observed resonance-like structures in the $π^{+} χ_{c 1}$ mass distribution, $Z_{1}^{+} (4050)$ and $Z_{2}^{+} (4250)$ , considered as $D^{*+}\bar{D}^{*…

The meson $Z^{+} (4430)$ as a tetraquark state

M. E. Bracco, S. H. Lee, M. Nielsen +1

We test the validity of the QCD sum rules applied to the meson $Z^{+} (4430)$ , by considering a diquark-antidiquark type of current with $J^{P} = 0^{-}$ and with $J^{P} = 1^{-}$ . We find…
