Performance of the ATLAS trigger system in 2015

Morad Aaboud, +2848 more
TL;DR: This paper presents a short overview of the changes to the trigger and data acquisition systems during the first long shutdown of the LHC and shows the performance of the trigger system and its components based on the 2015 proton–proton collision data.
Journal ArticleDOI

Differential branching fractions and isospin asymmetries of B -> K ((*)) μ(+) μ(-) decays

Roel Aaij, +713 more
TL;DR: In this article, the authors measured the isospin asymmetries of the B (0) -> K ( 0) mu (+) mu (-), B (1) → K (1)-m (+) m mu (-) and B (2)→ K (2)-m (-) m (-), respectively.
Journal ArticleDOI

Angular analysis of the B 0 → K *0 μ + μ − decay using 3 fb −1 of integrated luminosity

Roel Aaij, +764 more
TL;DR: An angular analysis of the B0 → K*0(→ K+π−)μ+μ− decay is presented in this paper, where the angular observables and their correlations are reported in bins of q2, the invariant mass squared of the dimuon system.
Journal ArticleDOI

Measurement of the fragmentation fraction ratio fs/fd and its dependence on B meson kinematics

Roel Aaij, +660 more
TL;DR: In this article, the relative production rate of B0s and B 0 mesons is determined with the hadronic decays B 0s→D−sπ+ and B0 → D − K +.
Journal ArticleDOI

Differential branching fraction and angular analysis of the decay B 0 → K ∗0 μ + μ −

Roel Aaij, +663 more
TL;DR: In this paper, the angular distribution and differential branching fraction of the decay of the dimuon system were studied using a data sample collected by the LHCb experiment in $pp$ collisions at $\sqrt{s}=7\,{\rm TeV}, corresponding to an integrated luminosity of 1.0
