      Oral report

      A near-threshold peaking structure, dubbed X(3960), is observed in the Ds+Ds- mass spectrum with significance greater than 12 standard deviations, using proton-proton collision data collected with the LHCb detector at centre-of-mass energies of 7, 8 and 13 TeV. Its quantum numbers is measured to be J^{PC}=0^{++} with the amplitude analysis. It may be a candidate with the quark content: c cbar...

      Oral report

      The first discovery of pentaquarks at LHCb in 2015, opens new window to study QCD. The LHCb experiment has the large dataset and excellent detector performance in such searches. In this talk, the latest results on pentaquark study in B-meson decays from LHCb will be discussed.

      Oral report
      Inspired by the observations of the pentaquark-like states found by LHCb, we investigated these heavy pentaquark states with the coupled channel unitary approach, taking into account the heavy quark spin symmetry and local hidden gauge symmetry. We dynamically reproduced three $P_c$ states and $P_{cs} (4459)$ in the interactions of the channels $\bar{D}^{(*)} \Sigma_c^{(*)}$ and $\bar{D}^{(*)}...

    7. 189. Lattice calculation of the $\eta_c\eta_c$ and $J/\psi J/\psi$ scattering length

      Oral report

      We calculate the s-wave scattering length in the $0^+$ sector of $\eta_c\eta_c$ and the $2^+$ sector of $J/\psi J/\psi$ using three $N_f=2$ twisted mass gauge ensembles
      with the lattice spacing $a=0.0667,0.085,0.098$ fm, respectively.
      The scattering lengths are extracted using the conventional L{\"u}scher finite size method. We observe significant discretization effects and therefore...
