Search for the decay B0s→ -D0 f0(980)

A search for B0 s → D 0 f0(980) decays is performed using 3.0 fb1− of pp collision data recorded by the LHCb experiment during 2011 and 2012. The f0(980) meson is reconstructed through its decay to the π +π − final state in the mass window 900 MeV/c2 < m(π +π −) < 1080 MeV/c2 . No significant signal is observed. The first upper limits on the branching fraction of B(B0 s → D 0 f0(980)) < 3.1 (3.4) × 10−6 are set at 90 % (95 %) confidence level.
