Workshop for young scientists with research interests focused on physics at FAIR

We review recent developments on the analysis of the Nucleon-Nucleon interaction with the corresponding propagation of statistical uncertainties originating from NN scattering experimental data. We also ponder on the consequences of this uncertainties on the predictive power of low energy chiral interactions and the required target numerical accuracy of nuclear structure calculations of light nuclei.

In this talk, the recent experimental and theoretical advances in the knowledge of the spectrum and structure of XYZ states will be reviewed, with special emphasis on the case of the $Z_c(3885)/Z_c(3900)$

The structure of heavy mesons located above the thresholds for the open flavour production as been largely discussed in the recent years. The observation of charged exotic states highlighted the importance of the light quark degrees of freedom in the description of both quarkonia and bottomonia. We will report the most recent experimental measurements performed by the Belle collaboration...

The BESIII Experiment at the Beijing Electron Positron Collider (BEPC2) collected large data samples for electron-positron collisions with center-of-mass above 4 GeV during 2013 and 2014. The analysis of these samples has resulted in a number of surprising discoveries, such as the discoveries of the electrically charged "Zc" structures, which, if resonant, cannot be accomodated in...

Quantum Chromodynamics (QCD), the theory of strong interactions, predicts several types of bound states. Among them are mesons (quark-antiquark) and baryons (quark-quark-quark), which have been the only states observed in experiments for years. However, in the last decade many states that do not fit this picture have been identified. There is growing evidence that at least some of the new...

There are several mesons whose $q\overline{q}$ quark-structure is doubted or even excluded. Therefore it is interesting to look for alternative structures for those candidates. Four-quark systems are a possible explanation. One way to approach four-quark models quantitatively is by means of lattice QCD. We study the heavy-light four-quark system $b\overline{b}l\overline{l}$ ($B\overline{B}$) on the lattice. The...
