Abstract

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 = 7 TeV 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
