Using data collected with the LHCb detector in proton–proton collisions at a centre-of-mass energy of 7 TeV, the hadronic decay is observed. This CP eigenstate mode could be used to measure mixing-induced CP violation in the system. Using a fit to the π+π− mass spectrum with interfering resonances gives . In the interval ±90 MeV around 980 MeV, corresponding to approximately two full f0 widths we also find , where in both cases the uncertainties are statistical and systematic, respectively.

    • [17] The CDF Collaboration limits the S-wave contribution within ±10 MeV of the φ mass to 6.7% at 95% confidence level. Their best fit value is 2% [3].
    • [18] We measure the K + K −π + yield from D+ decays. Then the φ yield is extracted and compared with the 0.28±0.05 measured fraction of K + K − within 20 MeV of the φ mass from the CLEO-c Dalitz analysis. See P. Rubin, et al., CLEO Collaboration, Phys. Rev. D 78 (2008) 072003. Finally we use the measured branching fraction ratio of K + K −π +/K +π −π + in D+ decays of (10.58 ± 0.29)% [11] to compare with Monte Carlo simulation.
