“…As stated previously, increasing the number of secondary vertices occurring outside of the target introduced a loss in tracking resolution due to the longer lever arm associated with a long segmented target. In order to recover some of this lost resolution FOCUS installed silicon microstrip detectors among the target elements [26]. This has the added advantage of providing measurement points closer to the interaction regions.…”

The purpose of this work is to improve the reconstruction techniques of the decays of the particles that contain charm in the quark composition using the information of the Target Silicon Detector of the experiment E831 (FOCUS). That experiment runs during 1997 to 1998 in Fermilab National Laboratory. The objective of the experiment was improving the understanding of the particles that contain charm. Adding the Target Silicon Detector information in the reconstruction process of the primary vertex the position error. This reduction produces an improvement in the mass signal and the knowledge of the charm particles properties. This ad to the possibility's that in other analysis will use the techniques developed in this work.

We review genetic programming principles, their application to FOCUS data samples, and use the method to study the doubly Cabibbo suppressed decay D + → K + π + π − relative to its Cabibbo favored counterpart, D + → K − π + π + . We find that this technique is able to improve upon more traditional analysis methods. To our knowledge, this is the first application of the genetic programming technique to High Energy Physics data.
