Resumen
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(D s + → π +μ +μ -)<4.1(4.8)×10 -7, B(D + → π -μ +μ +)<2.2(2.5)×10 -8, B(D s + → π -μ +μ +)<1.2(1.4)×10 -7. These limits are the most stringent to date.
