Abstract

Using a high statistics sample of photo-produced charm particles from the FOCUS experiment at Fermilab, we report results of a search for eight rare and Standard-Model-forbidden decays: D+, Ds+ → h±μμ+ (with h = π, K). Improvement over previous results by a factor of 1.7-14 is realized. Our branching ratio upper limit D+ → π+μ -μ+ of 8.8 × 10-6 at the 90% C.L. is below the current MSSM R-parity violating constraint.
