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

Size dependence of Young's modulus in ZnO nanowires.

TL;DR: A core-shell composite NW model in terms of the surface stiffening effect correlated with significant bond length contractions occurred near the {1010} free surfaces is proposed to explore the origin of the size dependence, and it is possible to estimate the size-related elastic properties of GaN nanotubes and relative nanostructures by using this model.
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

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

First Evidence for the Decay B-s(0) -> mu(+) mu(-)

Roel Aaij, +618 more
TL;DR: In this paper, a search for the rare decays Bs->mu+mu- and B0->Mu+Mu- is performed using data collected in 2011 and 2012 with the LHCb experiment at the Large Hadron Collider.
