A measurement of the ratios of the rates K L 0 →3π0K L 0 →π+π−π0, K L 0 →3π0K L 0 →all charged modes and K L 0 →πμvK L 0 →πev, and tests of the ΔI=1/2 rule

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...

Probing New Physics Via the Transverse Amplitudes of B 0 → K ∗ 0 ( → K − π + ) l + l − at Large Recoil

We perform an analysis of the K∗ polarization states in the exclusive B meson decay B0 → K∗0(→ K−π+)l+l− (l = e, μ, τ) in the low dilepton mass region, where the final vector meson has a large energy. Working in the transversity basis, we study various observables that involve the K∗ spin amplitudes A⊥, A‖, A0 by exploiting the heavyto-light form factor relations in the heavy quark and large-EK...
