Remarks on the penguin decay $B_s \to ϕϕ$ with prospects for FCCee

We underline the theoretical interest of the vector-vector penguin decay $B_s \to ϕϕ$, very clean from the experimental point of view. The CP-violation asymmetry $A_{CP}^{mix}$ comes from the interference of mixing and decay $λ_{ϕϕ} = {q \over p} {\bar{A} \over A}$. In the Standard Model (SM) and in the Naive Factorization limit, the CP phase from the mixing ${q \over p}$ exactly cancels the CP phase from the decay ratio ${\bar{A} \over A}$. Therefore, this mode is suitable to look for possible New Physics (NP) because $A_{CP}^{mix}$ would directly indicate the departure from the SM in mixing.…
