| dc.description | We apply a genetic programming technique to search for the double Cabibbo suppressed decays $Λ_c^+ \to p K^+ π^-$ and $D_s^+ \to K^+ K^+ π^-$. We normalize these decays to their Cabibbo favored partners and find $\text{BR}($Λ_c^+ \to p K^+ π^-$)/\text{BR}($Λ_c^+ \to p K^- π^+$) = (0.05 \pm 0.26 \pm 0.02)%$ and $\text{BR}($D_s^+ \to K^+ K^+ π^-$)/\text{BR}($D_s^+ \to K^+ K^- π^+$) = (0.52\pm 0.17\pm 0.11)%$ where the first errors are statistical and the second are systematic. Expressed as 90% confidence levels (CL), we find $< 0.46 % $ and $ < 0.78%$ respectively. This is the first successful use of genetic programming in a high energy physics data analysis. | |
