Searches for 25 Rare and Forbidden Decays of D+ and Ds+ Mesons ABSTRACT: A search is performed for rare and forbidden charm decays of the form D(s)+ → h± ℓ+ ℓ(′)∓, where h± is a pion or kaon and ℓ(′)± is an electron or muon. The measurements are performed using proton-proton collision data, corresponding to an integrated luminosity of 1.6 fb^−1, collected by the LHCb experiment in 2016. No evidence is observed for the 25 decay modes that are investigated and 90% confidence level limits on the branching fractions are set between 1.4 × 10^−8 and 6.4 × 10^−6. In most cases, these results represent an improvement on existing limits by one to two orders of magnitude.
