Abstract

A search for non-resonant D-(s)(+) -> pi(+)mu(+)mu(-) and D-(s)(+) -> pi(-)mu(+)mu(+) decays is performed using protonproton collision data, corresponding to an integrated luminosity of 1.0 fb(-1), at root 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 beB(D+ -> pi(+)mu(+)mu(-)) < 7.3 (8.3) x 10(-8),B(D-s(+) -> pi(+)mu(+)mu(-)) < 4.1 (4.8) x 10(-7),B(D-s(+) -> pi(+)mu(+)mu(-)) < 2.2 (2.5) x 10(-8),B(D-s(+) -> pi(+)mu(+)mu(-)) < 1.2 (1.4) x 10(-7).These limits are the most stringent to date.
