title: "Table 60 Covariance" of "Underlying-event studies with strange hadrons in $pp$ collisions at $\sqrt{s} = 13$ TeV with the ATLAS detector"

description: Statistical covariance between bins of Table 60
description: Properties of the underlying-event in $pp$ interactions are investigated primarily via the strange hadrons $K_{S}^{0}$, $\Lambda$ and $\bar\Lambda$, 
as reconstructed using the ATLAS detector at the LHC in minimum-bias $pp$ collision data at $\sqrt{s} = 13$ TeV.
The hadrons are reconstructed via the identification of the displaced two-particle vertices corresponding to the decay modes $K_{S}^{0}\rightarrow\pi^+\pi^-$, 
$\Lambda\rightarrow\pi^-p$ and $\bar\Lambda\rightarrow\pi^+\bar{p}$. 
These are used in the construction of underlying-event observables in azimuthal regions computed relative to the leading charged-particle jet in the event.
Events with a leading charged-particle jet in the range of $10 &lt; p_{T} \leq 40$ GeV are studied using the number of prompt charged particles in the transverse region.
