Study of Polarization in B -> VT Decays
Alakabha Datta, Yanyan Gao, Andrei V. Gritsan +3
In this paper, we examine B -> VT decays (V is a vector and T is a tensor meson), whose final-state particles can have transverse or longitudinal polarization. Measurements have be…
Testing Explanations of the Polarization Puzzle
Alakabha Datta, Andrei V. Gritsan, David London +2
($\btos$) is three separate decays, one for each polarization of the final-state vector mesons (one longitudinal, two transverse). It is observed that the fraction of tr…
Is There Still a B -> pi K Puzzle?
Seungwon Baek, David London
We perform a fit to the 2006 B -> pi K data and show that there is a disagreement with the standard model. That is, the B -> pi K puzzle is still present. In fact, it has gotten wo…
U-Spin Tests of the Standard Model and New Physics
Makiko Nagashima, Alejandro Szynkman, David London
Within the standard model, a relation involving branching ratios and direct CP asymmetries holds for the B-decay pairs that are related by U-spin. The violation of this relation in…
CP Violation in Supersymmetric Theories: stop2->stop1 H H, stop2->stop1 Z Z, stop2->stop1 W+ W-, stop2->stop1 Z H
Alejandro Szynkman, Ken Kiers, David London
We study the decays stop2->stop1 H H, stop2->stop1 Z Z, stop2->stop1 W+ W- and stop2->stop1 Z H, with an eye towards measuring the CP-violating supersymmetric parameters contained…
