Studies of Three-Body B^+→D ̅^* 〖(2007)〗^0 K^+ K ̅^0 and B^0→D^* 〖(2010)〗^- K^+ K ̅^0 Decays

We analyze three-body decays of and . Under the factorization approach, there are tree level diagrams for these decay modes and the transition matrix element of decay is factorized into a form factor multiplied by decay constant and form factor multiplied into weak vertices form factor. The transition matrix element of decay is also factorized into a form factor multiplied into weak vertic...

Comparison of D → K 0 S π and D → K 0 L π Decay Rates

We present measurements of D → K Sπ and D → K 0 Lπ branching fractions using 281 pb −1 of ψ(3770) data at the CLEO-c experiment. We find that B(D → K Sπ ) is larger than B(D → K Lπ ), with an asymmetry of R(D) = 0.108 ± 0.025 ± 0.024. For B(D → K Sπ ) and B(D → K Lπ ), we observe no measurable difference; the asymmetry is R(D) = 0.022±0.016±0.018. The D asymmetry is consistent with the value ba...

Study of the D 0 → K + K − π + π − decay

Using data from the FOCUS (E831) experiment at Fermilab, we present a new measurement for the Cabibbo-suppressed decay modeD0 → K+K−π+π−. We measure: Γ(D0 → K+K−π+π−)/Γ(D0 → K−π−π+π+) = 0.0295 ± 0.0011 ± 0.0008 . An amplitude analysis has been performed in order to determine the resonant substructure of this decay mode. The dominant components are the decays D0 → K1(1270) +K−, D0 → K1(1400) +K−...
