    We search for annihilation decay modes of neutral b mesons into pairs of charmless charged hadrons with the upgraded Collider Detector at the Fermilab Tevatron. Using a data sample corresponding to 6fb -1 of integrated luminosity, we obtain the first evidence for the Bs0→π +π - decay, with a significance of 3.7σ, and a measured branching ratio B(Bs0→π +π -)=(0.57±0.15(stat) ±0.10(syst))×10 -6. A search for the B0→K +K - mode in the same sample yields a significance of 2.0σ, and a central value estimate B(B0→K +K -)=(0.23±0.10(stat)±0.10(syst))×10 -6. © 2012 American Physical Society.
