Search for c+{expression} - > pK+- and Ds+{expression} - > K+K+- Using Genetic Programming Event Selection

We apply a genetic programming technique to search for the doubly Cabibbo suppressed decays c+{expression} - > pK+- and Ds+{expression} - > K+K+-. We normalize these decays to their Cabibbo favored partners and find BR(c+{expression} - > pK+-)/BR(c+{expression} - > pK-+) < 0.46% and B...

description We apply a genetic programming technique to search for the doubly Cabibbo suppressed decays c+{expression} - > pK+- and Ds+{expression} - > K+K+-. We normalize these decays to their Cabibbo favored partners and find BR(c+{expression} - > pK+-)/BR(c+{expression} - > pK-+) < 0.46% and BR(Ds+{expression} - > K+K+-)/BR(Ds+{expression} - > K-K++) < 0.78% at the 90% confidence level (CL). This is the first successful use of genetic programming in a high energy physics data analysis.
