Probing electroweak penguins through B^0(t) -> K_S K_S K_S
H. S. Mani, Nita Sinha, Rahul Sinha
This paper has been temporarily withdrawn, due to an error in Eq. (3).
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…
New Physics in B -> J/Psi K^*
D. London, N. Sinha, R. Sinha
Direct CP violation in B -> J/Psi K is a clean test for new physics. However, the direct CP asymmetry will vanish if the new-physics amplitude has the same strong phase as the stan…
Penguin Pollution in B->pi pi
Nita Sinha
In the presence of penguin contributions, the indirect CP asymmetry in B0(t)->pi+ pi- measures some effective (``polluted'') angle 2alpha_{eff}. The angle 2theta=2alpha_{eff}-2alph…
Searching for New Physics via CP Violation in B -> pi pi
D. London, N. Sinha, R. Sinha
We show how B -> pi pi decays can be used to search for new physics in the b -> d flavour-changing neutral current. One needs one piece of theoretical input, which we take to be a…
