“…In the past years, phenomenology models on the hadron spectroscopy evolved quickly and some patterns have been revealed, for example, dynamics close to two-hadron mass thresholds [616]. Besides, lattice QCD simulations have improved in computational performances and application scopes substantially over the years and will play more and more important roles in our understanding of low-energy QCD [617][618][619][620][621][622][623]. Hopefully, one day we can predict low energy QCD phenomena as precise as other parts of the SM.…”

Heavy flavour physics provides excellent opportunities to indirectly search for new physics at very high energy scales and to study hadron properties for deep understanding of the strong interaction. The LHCb experiment has been playing a leading role in the study of heavy flavour physics since the start of the LHC operations about ten years ago, and made a range of high-precision measurements and unexpected discoveries, which may have far-reaching implications on the field of particle physics. This review highlights a selection of the most influential physics results on CP violation, rare decays, and heavy flavour production and spectroscopy obtained by LHCb using the data collected during the first two operation periods of the LHC. The upgrade plan of LHCb and the physics prospects are also briefly discussed.

“…The most extensive lattice search for Z + c with mass below 4.2 GeV was performed in [27,37]. The major challenge is presented by the two-meson states J/ψ π, ψ 2S π, ψ 1D π, DD * , D * D * and η c ρ that are inevitably present in the I G (J PC ) = 1 + (1 +− ) channel, in addition to possible Z + c candidates.…”

Recent results on the hadron spectroscopy from lattice QCD are reviewed with emphasis on the meson sector and in particular on quarkonium-like XY Z states. I report on the first rigorous treatment of the near-threshold states X(3872) and D 0 s (2317), and the lattice searches for Z + c (3900), X(4140) and double-charm tetraquark states. Meson resonances in light, strange and charm sector are reviewed, where the resonances masses as well as the strong decay widths are reported. The first lattice QCD simulation of two coupled-channels is discussed.

“…Lattice QCD searched for evidence of a large tetraquark component in the closed-charm Z c (3940) − candidate but this resonance is well above threshold, and Ref. [18,19] concluded there is no robust lattice QCD evidence of a Z ± c tetraquark resonance. Lattice QCD also searched for the expected boundstate in light-lightantiheavy-antiheavy channels [20,21].…”

Lattice QCD static potentials of the meson-meson and tetraquark systems computed with both quenched and full QCD

et al. 2017

We revisit the static potential for the QQQQ system using SU(3) lattice simulations, studying both the color singlets' ground state and first excited state. We consider geometries where the two static quarks and the two antiquarks are at the corners of rectangles of different sizes. We analyze the transition between a tetraquark system and a two-meson system with a two by two correlator matrix. We compare the potentials computed with quenched QCD and with dynamical quarks. We also compare our simulations with the results of previous studies and analyze quantitatively fits of our results with Ansätze inspired in the string flip-flop model and in its possible color excitations.
