Vertex Reconstruction Performance of the ATLAS Detector at "\sqrt{s} = 13~\textrm{TeV}"

Early LHC Run-2 performance results of primary vertex reconstruction of the ATLAS experiment in proton-proton collisions at a centre-of-mass energy, "\sqrt{s} = 13~\textrm{TeV}" are presented. Some basic quantities are shown for two data taking periods, with different numbers of pp interactions, and are compared to Monte Carlo simulation. The vertex reconstruction efficiency and vertex position resolution are also measured in data and compared to Monte Carlo simulation. Good agreement is observed between data and simulation for some of the quantities presented, although some differences are observed in others.
