We present an analytic calculation of Branching Ratio (BR) and Charge-Parity (CP) violating asymmetries of the B s 0 ¯ meson decay into the two light vectors ϕ ϕ . In doing this we calculate the helicity amplitude of the present decay in the framework of QCD factorization approach. We find the BR of B s 0 ¯ ϕ ϕ = ( 1 . 56 ± 0 . 23 ) × 10 5 . We also calculate the direct CP violation, CP violation in mixing and CP violation due to interference which are A C P dir = 0 . 00355 ± 0 . 00152 , A C P mix = 0 . 00629 ± 0 . 03119 and A C P Δ Γ = 0 . 99997 ± 0 . 00019 , respectively. Our results are in agreement with the recent theoretical predictions and experimental measurements.
