# The perturbative QCD predictions for the decay B^{0}_{s}\rightarrow SS(a_{0}(980),f_{0}(980),f_{0}(500))

## TL;DR

This paper predicts decay rates and CP violations for specific B_s meson decays involving scalar mesons using perturbative QCD, providing results that can be tested in current experiments to understand scalar meson properties.

## Contribution

First calculation of these decay modes' branching ratios and CP violations in the pQCD framework considering scalar mesons as quark-antiquark states.

## Key findings

- Branching ratios are in the order of 10^{-4} to 10^{-6}.
- Predictions are accessible to LHCb experiments.
- Results aid understanding of scalar meson structure and QCD behavior.

## Abstract

In this work, we calculate the branching ratios and CP violations of the B^{0}_{s}\rightarrow a_{0}(980)a_{0}(980) decay modes with both charged and neutral a_{0}(980) mesons and B^{0}_{s}\rightarrow f_{0}(980)(f_{0}(500))f_{0}(980)(f_{0}(500)) for the first time in the pQCD approach. Considering the recent observation of the BESIII collaboration that provide a direct information about the constituent two-quark components in the corresponding a_{0}(980) wave functions, we regard the scalar mesons a_{0}(980), f_{0}(980) and f_{0}(500) as the q\bar{q} quark component in our present work, and then make predictions of these decay modes. The branching ratios of our calculations are at the order of the 10^{-4}\sim10^{-6} when we consider the mixing scheme. We also calculate the CP violation parameters of these decay modes. The relatively large branching ratios make it easily to be tested by the running LHC-b experiments, and it can help us to understand both the inner properties and the QCD behavior of the scalar meson.
