B -> pi pi Decays and New Physics
Seungwon Baek, David London
This paper has been withdrawn by the authors, due to a mistake which invalidates the analysis. One can never detect the presence of I=0 new physics in B -> pi pi.
New-Physics Signals in B -> pi pi Decays

Determining weak phases using B->D^*V Decays
David London, Nita Sinha, Rahul Sinha
We describe how the angular analysis of vector-vector final states in B decays provides theoretically clean techniques for determination of CP violating phases. The quantity $\sin^…
Signals of New Physics using angular analysis in B -> V1 V2 decays
David London, Nita Sinha, Rahul Sinha
We show that an angular analysis of B -> V1 V2 decays yields numerous tests for new physics in the decay amplitudes. Many of these new-physics observables are nonzero even if the s…
T violation in Decays in the SM and Beyond
Alakabha Datta, David London
In this talk, we describe T-violating triple-product correlations (TP's) in decays. We point out that TP's in the SM are generally tiny. It is only in a few decays…
New Physics and B -> V1 V2 Decays
David London
I discuss several techniques for observing new physics using measurements of B -> V1 V2 decays. Within the standard model, all CP-violating triple-product correlations (TP's) invol…
