Effective field theory for threshold phenomena

N. Brambilla (TUM) / Y. Jia (IHEP)

Summary

In the second funding period we want to take advantage of the results that we obtained in the first period of the project and of the advancements that took place in the last few years in the implementation of multiquark and scattering states on the lattice and in the construction of EFTs, to aim at achieving a comprehensive and QCD based description of the structure of the exotic X, Y, Z  quarkonium states in the region close to the open strong decay threshold in the hadronic sector containing a heavy quark and a heavy antiquark.
