23. “The coupled channel system D*D*-DD* and decays of doubly charm mesons molecules”

Dr Raquel Molina (The George Washington University)

Section C: Heavy Quarks

Several observed states close to the D\bar{D}^* and D^*_{(s)}\bar{D}^*_{(s)} thresholds, as the X(3872) and some XYZ particles can be described in terms of a two-meson molecule. Furthermore, doubly charmed states are also predicted, named as R_{cc}(3970) and S_{cc}(4100). These new states are near the DD^*, D^*D^* and D^*D^*_s thresholds. We compute decays into DD\pi and radiative decays of...

Section C: Heavy Quarks

Hadron as an impurity bound in nuclei causes interesting phenomena which do not emerge in normal nuclei. These effects would give us the information not only on the internal structure of the nuclei, but also on the changing properties of the impurity in the nuclear medium. The hadron-nucleus systems have been studied in the light flavor sector, especially. However, a strong...

81. Hadronic Molecules in the Heavy Baryon Spectrum

David R. Entem (University of Salamanca)

Section C: Heavy Quarks

We study possible baryon molecules in the non-strange heavy baryon spectrum. We include configurations with a heavy-meson and a light baryon. We find several structures, in particular we can understand the $\Lambda_c(2940)$ as a $D^{\ast} N$ molecule with $J^P=3/2^-$ quantum numbers. We also find $D^{(\ast)} \Delta$ candidates for the recently discovered $X_c(3250)$ and $X_c(3212)$ resonances.

206. The recent result about Charmonium (like) states at BESIII

Dr Weimin Song (IHEP)

09/09/2014, 17:30

Section C: Heavy Quarks

The result results about Charmonium states ( etac(2S)... ) and Charmonium-like states ( Zc(3900)...) studied at BESIII will mentioned in the talk.

239. A New Hadron Spectroscopy

Prof. Stephen Lars Olsen (Center for Underground Physics)

Section C: Heavy Quarks

Recently,  many candidate multiquark mesons, i.e., mesons with substructures that are more complex that the quark-antiquark prescription that is in the textbooks, have been observed.  Many of the most recently observed candidate states are electrically charged and have the same spin and parity, namely JP=1+. In this talk I will give an overview of the current experimental situation and try to...
