Abstract

Properties of the underlying-event in pp interactions are investigated primarily via the strange hadrons KS0, Λ and Λ¯, as reconstructed using the ATLAS detector at the LHC in minimum-bias pp collision data at s=13 TeV. The hadrons are reconstructed via the identification of the displaced two-particle vertices corresponding to the decay modes, Λ→π-p and Λ¯→π+p¯. These are used in the construction of underlying-event observables in azimuthal regions computed relative to the leading charged-particle jet in the event. None of the hadronisation and underlying-event physics models considered can describe the data over the full kinematic range considered. Events with a leading charged-particle jet in the range of 10
