Relations for two body B Decays to Charmonium and tests for mixing
Alakabha Datta, Harry J. Lipkin, Patrick J. O'Donnell
The two body decays of and decays into , where is a light meson, is studied under the very simple assumptions that the spectator quark does not play a role in…
Using Bs(t) -> phi K_s to measure Sin 2 beta
Alakabha Datta, C. S. Kim, David London
In this talk we show that, unlike other pure penguin processes, the decay $\bs(t)\toϕ\ks$ is dominated by a single amplitude, that of the internal -quark. Thus, the ind…
B -> K(*) Kbar(*) Decays: A New Method for Measuring the CP Phase α
Alakabha Datta, David London
We present a new method for measuring the CP phase α. It requires the measurement of the pure penguin decays Bd(t) -> K(*) Kbar(*) and B_s -> K(*) Kbar(*). The method is quite clea…
Difficulties in Obtaining Weak Phases from Penguin Decays
Alakabha Datta, C. S. Kim, David London
We re-examine a recent proposal for obtaining βusing the measurements of the b -> d penguin decays B_d(t) -> K^0 \kbar and B_s(t) -> ϕK_S, along with a theoretical assumption. We s…
Measuring sin 2βin Bs(t) -> phi K_s
Alakabha Datta, C. S. Kim, David London
We show that, unlike other pure b -> d penguin processes, the decay Bs(t) -> phi K_s is dominated by a single amplitude, that of the internal t-quark. The contributions of the u- a…
Weak decays to final states with Radial Excitation Admixtures
Alakabha Datta, Harry J. Lipkin, Patrick J. O'Donnell
We consider the weak decays of a B meson to final states that are mixtures of S-wave radially excited components. We consider non leptonic decays of the type ,…
