Abstract:
We apply a genetic programming technique to search for the \dcs decays \dskkpidcsd and \pkpidcsd. We normalize these decays to their \cf partners and find that $\text{BR}(\pkpidcsd)/\text{BR}(\pkpi) < 0.46\%$ and $\text{BR}(\dskkpidcsd)/\text{BR}(\dskkpi) < 0.78\%$, both at the 90\% confidence level. This is the first successful use of genetic programming in a high energy physics data analysis.
