Title: Measurement of the branching ratio for the doubly cabibbo suppressed decay D ++ K -K +K +; Medida da razao de ramificacao do Decaimento D ++ K -K +K + duplamente suprimido por cabibbo (in Portuguese)

Abstract

In this thesis, we performed a study for the decay modes D ++ K -K +K + and D + s+ K -K +K +, using the data collected by the E791, a hadroproduction of charm experiment at Fermilab. The D ++ K -K +K + decay is doubly Cabibbo suppressed while the D + s+ K -K +K + decay is singly Cabibbo suppressed. We found 11.6 +- 3.9 events in the D + mass region and 8.9 +- 3.3 in the D + s mass region. The D ++ K -K +K + branching ratio is measured to be (3.7 +- 1.3 +- 0.6) x 10 -4 while the D ++ K -K +K + branching ratio relative to D + s+ K -K +K + is measured to be (4.2 +- 1.5 +- 0.6) x 10 -2.
