Electroweak precision constraints on the Lee-Wick Standard Model
Ezequiel Alvarez, Leandro Da Rold, Carlos Schat +1
We present the constraints on the parameter space of the Lee-Wick Standard Model coming from electroweak precision observables. The model predicts a large positive S and a negative…
Polarization Studies: testing explanations of the B -> phi K* puzzle and B -> V T decays
Alejandro Szynkman
It has been observed in B->phiK* and B^{0(+)}->rho^{0(+)}K^{*0} that the fraction of transverse decays, fT, and the fraction of longitudinal decays, fL, are roughly equal, in oppos…
Electroweak precision constraints on the Lee-Wick Standard Model
Ezequiel Alvarez, Leandro Da Rold, Carlos Schat +1
We perform an analysis of the electroweak precision observables in the Lee-Wick Standard Model. The most stringent restrictions come from the S and T parameters that receive import…
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…
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…
