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 s sbar candidate.
