The BABAR detector

Bernard Aubert, +819 more
TL;DR: BABAR as discussed by the authors is a detector for the SLAC PEP-II asymmetric e+e-B Factory operating at the upsilon 4S resonance, which allows comprehensive studies of CP-violation in B-meson decays.
Journal ArticleDOI

Search for the lepton flavour violating decay μ + → e + γ with the full dataset of the MEG experiment

A. M. Baldini, +93 more
TL;DR: The final results of the search for the lepton flavour violating decay were presented in this paper, based on the full dataset collected by the MEG experiment at the Paul Scherrer Institut in the period 2009-2013.
Journal ArticleDOI

Evidence for an excess of B̄→D( *)τ -ν ̄τ decays

J. P. Lees, +365 more
TL;DR: In this article, the BaBar data sample was used to investigate the sensitivity of BaBar ratios to new physics contributions in the form of a charged Higgs boson in the type II two-Higgs doublet model.
Journal ArticleDOI

Measurement of an excess of B̄→D(*) τ-ν̄τ decays and implications for charged Higgs bosons

J. P. Lees, +340 more
- 31 Oct 2013 - 
TL;DR: The concept for this analysis is to a large degree based on earlier BABAR work and we acknowledge the guidance provided by M. Mazur as discussed by the authors, who consulted with theorists A. Datta, S. Westhoff,S. Fajfer, J. Kamenik, and I. Nisandzic on the calculations of the charged Higgs contributions to the decay rates.
Journal ArticleDOI

New Constraint on the Existence of the μ + → e + γ Decay

TL;DR: The data collected by the MEG experiment at the Paul Scherrer Institut show no excess of events compared to background expectations and yield a new upper limit on the branching ratio of this decay of 5.7 × 10(-13) (90% confidence level).
