Supersymmetric Contributions to Bs->K+K-
Seungwon Baek, David London, Joaquim Matias +1
Inspired by the existing calculation of B->piK decays in supersymmetry (SUSY), we evaluate the dominant SUSY contributions to Bs->K+K-. We show that the observables of this process…
Measurements of New Physics in B -> pi pi Decays
Seungwon Baek, F. J. Botella, David London +1
If new physics (NP) is present in B -> pi pi decays, it can affect the isospin I=2 or I=0 channels. In this paper, we discuss various methods for detecting and measuring this NP. T…
Polarization States in B -> rho K* and New Physics
Seungwon Baek, Alakabha Datta, Philippe Hamel +2
The standard-model explanations of the anomalously-large transverse polarization fraction fT in B -> phi K* can be tested by measuring the polarizations of the two decays B+ -> rho…
Can one detect new physics in I=0 and/or I=2 contributions to the decays B --> pi pi?
Seungwon Baek, F. J. Botella, David London +1
We study the effects of new-physics contributions to B --> pi pi decays, which can be parametrized as four new complex quantities. A simple analysis is provided by utilizing the re…
Dynamical CP Violation in the Early Universe and Leptogenesis
K. R. S. Balaji, Tirthabir Biswas, Robert H. Brandenberger +1
In a recent publication, we suggested a mechanism for obtaining dynamical CP violation in the early Universe based on the out-of-equilibrium evolution of complex scalar fields. In…
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This paper has been withdrawn by the authors, due to a mistake which invalidates the analysis.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.
