Interpretation of Yb(10750) as a tetraquark and its production mechanism
Recently, the Belle Collaboration has updated the analysis of the cross sections for the processes e+e−→ϒ(nS)π+π− (n=1,2,3) in the e+e− center-of-mass energy range from 10.52 to 11.02 GeV. A new structure, called here Yb(10750), with the mass M(Yb)=(10752.7±5.9−1.1+0.7) MeV and the Breit-Wigner widt...
