Resumen

Based on (10087 ± 44) × 10⁶J/ψ events recorded with the BESIII detector, we search for the rare charmonium weak decays J/ψ→Ds−ρ++c.c. and J/ψ→Ds−π++c.c. No signal is observed, and upper limits on the branching fractions at the 90% confidence level are set as BJ/ψ→Ds−ρ++c.c.<8.0×10−7 and BJ/ψ→Ds−π++c.c.<4.1×10−7. Our results provide the most stringent experimental constraints on these decays.
