Rescattering Contributions to rare B-Meson Decays
Michael Gronau, David London, Jonathan L. Rosner
Several and decays have been observed which have been cited as evidence for exchange (), penguin annihilation () and annihilation () processes, such as $\bar b…
Revisiting D0-D0bar mixing using U-spin
Michael Gronau, Jonathan L. Rosner
We prove that - mixing in the standard model occurs only at second order in U-spin breaking. The U-spin subgroup of SU(3) is found to be a powerful tool for analyzin…
Nonleptonic Charm Decays and CP Violation
Bhubanjyoti Bhattacharya, Michael Gronau, Jonathan L. Rosner
In this talk we briefly present a flavor-SU(3) technique to study branching ratios and direct CP asymmetries -meson decays. The first part of the talk is meant to set up a found…
Direct CP Violation in D Decays in view of LHCb and CDF Results
Bhubanjyoti Bhattacharya, Michael Gronau, Jonathan L. Rosner
The LHCb and CDF Collaborations have recently reported evidence for a CP asymmetry around -0.7% in , the difference between and $A_{CP}(D^0 \to π…
Non-factorizable effects in top quark production
Jonathan L. Rosner
The production of top-antitop pairs at the Fermilab Tevatron shows a forward-backward asymmetry in which the top quark tends to follow the proton direction, while the antitop tends…
Prospects for improved branching fractions
Jonathan L. Rosner
The experimental uncertainty on the branching fraction $\b(Λ_c \to p K^- π^+) = (5.0 \pm 1.3)%$ has not decreased since 1998, despite a much larger data sample. Uncertainty in this…
Flavor-SU(3) tests from and Dalitz plots
Bhubanjyoti Bhattacharya, Jonathan L. Rosner
The processes and $D^0\to\ok K^+π^-$ involve intermediate vector resonances whose amplitudes and phases are related to each other via flavor-SU(3) symmetry. Dal…
CP asymmetries in singly-Cabibbo-suppressed decays to two pseudoscalar mesons
Bhubanjyoti Bhattacharya, Michael Gronau, Jonathan L. Rosner
The LHCb Collaboration has recently reported evidence for a CP asymmetry approaching the percent level in the difference between and . We analyze…
