Exotic meson-meson molecules and compact four–quark states
We present an exact calculation of S and P wave QQn̄n̄ states using different standard nonrelativistic quark–quark potentials. We explore in detail the charm and bottom sectors looking for bound states that could be measured within existing facilities. Against the proliferation of four–quark states sometimes predicted in the literature, we found a small number of candidates to be stable. We analy...
متن کاملHistory of Exotic Meson (4-quark) and Baryon (5-quark) States
I briefly review the history of exotic meson (4-quark) and baryon (5quark) states, which is rooted in the formalism of Regge pole and duality. There are robust model-independent predictions for the exchange of 4-quark (Baryonium) Regge trajectories in several processes, which are strongly supported by experiment. On the other hand the predictions for the spectroscopy of 4-quark resonances are b...
متن کاملEfficient computation of meson and four-quark correlation functions
This work deals with the efficiency of different methods for computing correlation functions of bound states in twisted mass lattice QCD with Nf = 2 flavors of seaquarks. In particular, the focus will be on pseudo-scalar and scalar meson correlators as well as correlation functions generated by a four-quark operator. The main part of this thesis will be the comparison of three methods used to c...
متن کاملExotic states of matter in heavy meson decays 1
The decays of mesons containing heavy quarks provide carefully controlled environments for production of hadronic states with specific quantum numbers. Copious samples of such mesons accumulated at the BaBar, Belle, and CLEO detectors permit searches for interesting forms of matter, including mesons beyond the usual quark-antiquark and baryons beyond the usual three-quark configurations. Such h...
