Abstract: (Elsevier)
A search for non-resonant D(s)+→π+μ+μ− and D(s)+→π−μ+μ+ decays is performed using proton–proton collision data, corresponding to an integrated luminosity of 1.0 fb −1 , at s=7TeV recorded by the LHCb experiment in 2011. No signals are observed and the 90% (95%) confidence level (CL) limits on the branching fractions are found to be B(D+→π+μ+μ−)<7.3(8.3)×10−8, B(Ds+→π+μ+μ−)<4.1(4.8)×10−7, B(D+→π−μ+μ+)<2.2(2.5)×10−8, B(Ds+→π−μ+μ+)<1.2(1.4)×10−7. These limits are the most stringent to date.Note:
