We present the first measurement of polarization and
CP-violating asymmetries in a B(s)0 decay into two light vector mesons,
B(s)0→ϕϕ, and an improved determination of its branching ratio using
295 decays reconstructed in a data sample corresponding to 2.9 fb-1
of integrated luminosity collected by the CDF experiment at the Fermilab
Tevatron collider. The fraction of longitudinal polarization is determined
to be fL=0.348±0.041(stat)±0.021(syst), and the branching ratio
B(B(s)0→ϕϕ)=[2.32±0.18(stat)±0.82(syst)]×10-5. Asymmetries
of decay angle distributions sensitive to CP violation
are measured to be Au=-0.007±0.064(stat)±0.018(syst) and
Av=-0.120±0.064(stat)±0.016(syst).
