The hidden-charm pentaquark and tetraquark states

In the past decade many charmonium-like states were observed experimentally. Especially those charged charmoniumlike Z c states and bottomonium-like Z b states can not be accommodated within the naive quark model. These charged Z c states are good candidates of either the hidden-charm tetraquark states or molecules composed of a pair of charmed mesons. Recently, the LHCb Collaboration discovered two hidden-charm pentaquark states, which are also beyond the quark model. In this work, we review the current experimental progress and investigate various theoretical interpretations of these candidates of the multiquark states. We list the puzzles and theoretical challenges of these models when confronted with the experimental data. We also discuss possible future measurements which may distinguish the theoretical schemes on the underlying structures of the hidden-charm multiquark states.

“…The discovery of the X(3872) has led to a resurgence of interest in exotic spectroscopy and subsequently many new states have been claimed. [547][548][549], and not confirmed by BaBar [550,551]. The nature of these states has drawn much theoretical attention and many models have been proposed.…”

region at a hadron collider. This document discusses the implications of these first measurements on classes of extensions to the Standard Model, bearing in mind the interplay with the results of searches for on-shell production of new particles at ATLAS and CMS. The physics potential of an upgrade to the LHCb detector, which would allow an order of magnitude more data to be collected, is emphasised.

“…Therefore, it is worth inspecting the Λ 0 b → J=ψpK − data with an approach that is model independent with respect to K − p contributions. Such a method was introduced by the BABAR Collaboration [13] and later improved upon by the LHCb Collaboration [14]. There it was used to examineB 0 → ψð2SÞπ þ K − decays, which are dominated by kaon excitations decaying to K − π þ , in order to understand whether the data require the presence of the tetraquark candidate decay, Zð4430Þ þ → ψð2SÞπ þ .…”
