T violation in $B \to V V$ Decays in the SM and Beyond

Alakabha Datta, David London

In this talk, we describe T-violating triple-product correlations (TP's) in $B \to V_{1} V_{2}$ decays. We point out that TP's in the SM are generally tiny. It is only in a few decays…

Single Top Production and Extra Dimensions

Alakabha Datta

In extra dimension theories, where the gauge bosons of the standard model propagate in the bulk of the extra dimensions, there are Kaluza-Klein excitations of the standard model ga…

Measuring alpha using B -> K() Kbar() Decays

Alakabha Datta, David London

We describe a new method for obtaining the CP phase alpha via measurements of B_{d,s} -> K(*) Kbar(*) decays. This method is particularly appropriate for hadron colliders since som…

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 $b \to d$ penguin processes, the decay $\bs(t)\toϕ\ks$ is dominated by a single amplitude, that of the internal $t$ -quark. Thus, the ind…

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 $B \to ρ^{'} π / B \to ρ π$ ,…

Flavor Changing Decays of $Υ$ and $J / ψ$

Alakabha Datta

We study flavor changing processes $Υ \to B / B ˉ X_{s}$ and $J / ψ \to D / D ˉ X_{u}$ in the B factories and the Tau-Charm factories. In the standard model, these processes are pred…
