Description:
Author(s): A. Ali, L. Maiani, A. D. Polosa, and V. Riquer Assuming the dominance of the spin-spin interaction in a diquark, we point out that the mass difference in the beauty sector M(Z b ′ ) ± -M(Z b ) ± scales with quark masses as expected in QCD, with respect to the corresponding mass difference M(Z c ′ ) ± -M(Z c ) ± . Notably, we show that the decays ϒ(10890)→ϒ(nS)π + ... [Phys. Rev. D 91, 017502] Published Tue Jan 06, 2015
