Journal ArticleDOI

Heavy quarkonium: progress, puzzles, and opportunities

Nora Brambilla, +69 more
TL;DR: The early years of this period were chronicled in the Quarkonium Working Group (QWG) CERN Yellow Report (YR) in 2004, which presented a comprehensive review of the status of the field at that time and provided specific recommendations for further progress as mentioned in this paper.
Journal ArticleDOI

Test of lepton universality using b^{+}k^{+}ℓ^{+}ℓ^{-} decays

Roel Aaij, +701 more
TL;DR: The value of the ratio of branching fractions for the dilepton invariant mass squared range 1 < q(2) < 6 GeV(2)/c(4) is measured to be 0.745(-0.074)(+0.090)(stat) ± 0.036(syst).
Journal ArticleDOI

LHCb detector performance

Roel Aaij, +703 more
TL;DR: In this paper, the performance of the various LHCb sub-detectors and the trigger system are described, using data taken from 2010 to 2012, and it is shown that the design criteria of the experiment have been met.
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

Test of lepton universality with B 0 → K *0 ℓ + ℓ − decays

Roel Aaij, +821 more
TL;DR: In this article, a test of lepton universality is performed by measuring the ratio of the branching fractions of the B$0$ → K$*0}$ e$+}$ π$−}$ decays, and the ratio is measured in two regions of the dilepton invariant mass squared.
