Infinitesimally Robust Estimation in General Smoothly Parametrized Models
Full text linkWe describe the shrinking neighborhood approach of Robust Statistics, which
applies to general smoothly parametrized models, especially, exponential
families. Equal generality is achieved by object oriented implementation of the
optimally robust estimators. We evaluate the estimates on real datasets from
literature by means of our R packages ROptEst and RobLox

Measurement of CP-Violating Asymmetries in B0 Decays to CP Eigenstates
Get PDFWe present measurements of time-dependent CP-violating asymmetries in neutral B decays to several CP eigenstates. The measurement uses a data sample of 23×10^6 ϒ(4S)→BB̅ decays collected by the BABAR detector at the PEP-II asymmetric B Factory at SLAC. In this sample, we find events in which one neutral B meson is fully reconstructed in a CP eigenstate containing charmonium and the flavor of the other neutral B meson is determined from its decay products. The amplitude of the CP-violating asymmetry, which in the standard model is proportional to sin2β, is derived from the decay time distributions in such events. The result is sin2β = 0.34±0.20(stat)±0.05(syst)
