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…

Flavour-Changing Neutral Currents and Leptophobic Z' Gauge Bosons

Karine Leroux, David London

Leptophobic Z' gauge bosons can appear in models with an E_6 gauge symmetry. We show that flavour-changing neutral currents can be generated in some of these models due to the mixi…

Improving Bounds on Penguin Pollution in B -> pi pi

Michael Gronau, David London, Nita Sinha +1

In the presence of penguin contributions, the indirect CP asymmetry in B0(t) -> pi+ pi- measures sin(2α+ 2θ), where 2θparametrizes the size of the penguin ``pollution.'' We derive…

Detection of a Hypercharge Axion in ATLAS

Erik Elfgren

This Master of Science thesis treats the hypercharge axion, which is a hypothetical pseudo-scalar particle with electroweak interactions. First, the theoretical context and the mot…

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…

Extracting Weak Phase Information from B -> V_1 V_2 Decays

D. London, N. Sinha, R. Sinha

We describe a new method for extracting weak, CP-violating phase information, with no hadronic uncertainties, from an angular analysis of B -> V_1 V_2 decays, where V_1 and V_2 are…

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…
