Description
The Bs0→J/ψφ and Bs0→J/ψf0(980) decays are analyzed within generalized QCD factorization including all leading-order corrections in αs: We point out that the ratio of our calculated widths, Γ(Bs0→J/ψf0(980), f0(980)→π+π-)/Γ(Bs0→J/ψφ,φ→K+K-), strongly indicates that S-wave effects in the f0(980)'s daughter pions or kaons cannot be ignored in the extraction of the Bs-Bs mixing angle, -2βs, from the Bs0→φJ/ψ decay amplitudes.
