Bs-->K+K- and Bs-->K0 anti-K0 Decays within Supersymmetry
Seungwon Baek, David London, Joaquim Matias +1
We compute the supersymmetric (SUSY) contributions to the observables in Bs-->K+K- and Bs-->K0 anti-K0 decays. The hadronic parameters in the standard-model (SM) amplitudes are obt…
Direct test of time reversal invariance violation in B mesons
Ezequiel Alvarez, Alejandro Szynkman
In this letter we reinterpret and reanalyze the available data of the B meson factories showing the existence of direct experimental evidence of time reversal invariance violation…
Extracting alpha from B0(d) --> K0 anti-K0 Decays
Alakabha Datta, Maxime Imbeault, David London +1
We propose a new method for obtaining the CP phase alpha, based on measurements of B0(d) --> K0 anti-K0, along with theoretical input. Due to the similarities of QCD factorization…
Fourth Generation CP Violation Effect on B -> K pi, phi K and rho K in NLO PQCD
Wei-Shu Hou, Hsiang-nan Li, Satoshi Mishima +1
We study the effect from a sequential fourth generation quark on penguin-dominated two-body nonleptonic B meson decays in the next-to-leading order perturbative QCD formalism. With…
Large Time-dependent CP Violation in B_s^0 System and Finite D^0-D^0bar Mass Difference in Four Generation Standard Mode
Wei-Shu Hou, Makiko Nagashima, Andrea Soddu
Combining the measured B_s mixing with b \to s\ell^+\ell^- rate data, we find a sizable 4 generation t' quark effect is allowed, for example with m_{t'} \sim 300 GeV and V_{t's}^*V…
CP Violation in Hadronic tau Decays
Alakabha Datta, Ken Kiers, David London +2
We re-examine CP violation in the Delta S = 0 decays tau -> N pi nu_tau (N=2,3,4). We assume that the new physics (NP) is a charged Higgs. We show that there is no NP contribution…
Patterns of New Physics in B Decays
Maxime Imbeault, David London, Chandradew Sharma +2
We show that any new physics (NP) which affects B decays with penguin contributions can be absorbed by redefinitions of the standard-model (SM) diagrammatic amplitudes. Hence, ther…
CP Violation in Supersymmetric Theories: stop2 -> stop1 tau- tau+
Ken Kiers, Alejandro Szynkman, David London
Supersymmetric (SUSY) theories include many new parameters, some of which are CP-violating. Assuming that SUSY is found at a future high-energy collider, we examine the decay stop2…
Canonical Constraints on Leptonic Cp Violation using UHCR neutrino fluxes
K. R. S. Balaji, G. Couture, C. Hamzaoui
It is shown that one can in principle constrain the CP-violating parameter delta from measurements of four independant |V_{ij}|^2, or three of them and a ratio, in the leptonic sec…
Hadronic B Decays: A General Approach
Maxime Imbeault, Alakabha Datta, and David London
In this paper, we propose a general approach for describing hadronic B decays. Using this method, all amplitudes for such decays can be expressed in terms of contractions, though t…
Perturbative and Nonperturbative Contributions to a Simple Model for Baryogenesis
K. R. S. Balaji, Bjorn Garbrecht
Single field baryogenesis, a scenario for Dirac leptogenesis sourced by a time-dependent scalar condensate, is studied. We compare the creation of the charge asymmetry by the pertu…
Constraints on B and Higgs Physics in Minimal Low Energy Supersymmetric Models
M. Carena, A. Menon, R. Noriega-Papaqui +2
We study the implications of minimal flavor violating low energy supersymmetry scenarios for the search of new physics in the B and Higgs sectors at the Tevatron collider and the L…
Looking for Delta I = 5/2 amplitude components in B -> pi pi and B -> rho rho experiments
F. J. Botella, David London, Joao P. Silva
We discuss how experiments measuring B -> pi pi and B -> rho rho may be used to search for a Delta I = 5/2 amplitude component. This component could be the explanation for a recent…
