Study of f0(980) and f0(1500) from Bs → f0(980)K, f0(1500)K decays

Abstract

In this paper, we calculate the branching ratios and CP-violating asymmetries for within the perturbative QCD approach based on kT factorization. If the mixing angle θ falls into the range of 25° < θ < 40°, the branching ratio of is while θ lies in the range of 140° < θ < 165°, is about 6.5 × 10−7. As to the decay , when the mixing scheme for f0(1500) is used, it is difficult to determine which scenario is more preferable from the branching ratios for these two scenarios because they are both close to 1.0 × 10−6. But there exists a large difference in the form factor for the two scenarios.
