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

Observation of a broad structure in the pi(+)pi(-)J/psi mass spectrum around 4.26 GeV/c(2)

Bernard Aubert, +634 more
TL;DR: Fits to the mass spectrum indicate that a broad resonance with a mass of about 4.26 GeV/c2 is required to describe the observed structure, and the presence of additional narrow resonances cannot be excluded.
Journal ArticleDOI

High Statistics Measurement of the Positron Fraction in Primary Cosmic Rays of 0.5-500 GeV with the Alpha Magnetic Spectrometer on the International Space Station

L. Accardo, +311 more
TL;DR: The new results show, for the first time, that above ∼200 GeV the positron fraction no longer exhibits an increase with energy.
Journal ArticleDOI

Searches for Lepton Flavor Violation in the Decays tau(+/-) -> e(+/-)gamma and tau(+/-) -> mu(+/-)gamma

Bernard Aubert, +491 more
TL;DR: In this article, the authors performed searches for lepton-flavor-violating decays of a tau lepton to a lighter mass lepton and a photon with the entire data set of (963 +/- 7) x 10(6) tau decays collected by the BABAR detector near the Y(4S), Y(3S) and Y(2S) resonances.
