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.

Observation of $J/\psi p$ Resonances Consistent with Pentaquark States in $\Lambda_b^0 \to J/\psi K^- p$ Decays

Roel Aaij, +722 more
TL;DR: In this article, the pentaquark-charmonium states were observed in the J/ψp channel in Λ0b→J/K−p decays and the significance of these resonances is more than 9 standard deviations.
Journal ArticleDOI

The LHCb trigger and its performance in 2011

Roel Aaij, +85 more
TL;DR: The LHCb trigger and its performance based on data taken at the LHC in 2011 is presented in this article, where a combination of lepton identification of particles, transverse momentum of particles and selects particles originating from hadrons which decay after a finite flight distance.
