Pertubative QCD in Bs $ \rightarrow$ $ \phi$ $ \phi$

Abstract

In this research, the hadronic decay of \( B_{s}\rightarrow \phi \phi\) is analyzed by using the QCD factorization (QCDF) and pertubative QCD (pQCD). The experimental branching ratio of this decay is \( 1.9\times 10^{-5}\) and our results according to the QCDF method and pQCD are \( (0.05\pm 0.02)\times 10^{-5}\) and \( (1.7\pm 0.01)\times 10^{-5}\) , respectively. We consider that the branching ratio of pQCD is in agreement with available experimental data.
