Abstract

A search for non-resonant D<inf>(s)</inf><sup>+</sup> → π<sup>+</sup>μ<sup>+</sup>μ<sup>-</sup> and D<inf>(s)</inf><sup>+</sup> → π<sup>-</sup>μ<sup>+</sup>μ<sup>+</sup> decays is performed using proton-proton collision data, corresponding to an integrated luminosity of 1.0 fb<sup>-1</sup>, √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<sup>+</sup> → π<sup>+</sup>μ<sup>+</sup>μ<sup>-</sup>)<7.3(8.3)×10<sup>-8</sup>, B(D<inf>s</inf><sup>+</sup> → π<sup>+</sup>μ<sup>+</sup>μ<sup>-</sup>)<4.1(4.8)×10<sup>-7</sup>, B(D<sup>+</sup> → π<sup>-</sup>μ<sup>+</sup>μ<sup>+</sup>)<2.2(2.5)×10<sup>-8</sup>, B(D<inf>s</inf><sup>+</sup> → π<sup>-</sup>μ<sup>+</sup>μ<sup>+</sup>)<1.2(1.4)×10<sup>-7</sup>. These limits are the most stringent to date. © 2013 CERN.
