Query: Strangeness of the nucleon from Lattice Quantum Chromodynamics   We present a non-perturbative calculation of the strangeness of the nucleon
$y_N$ within the framework of lattice QCD. This observable is known to be an
important cornerstone to interpret results from direct dark matter detection
experiments. We perform a lattice computation for $y_N$ with an analysis of
systematic effects originating from discretization, finite size, chiral
extrapolation and excited state effects leading to the value of $y_N=
0.173(50)$. The rather large uncertainty of this value of $y_N$ is dominated by
systematic uncertainties which we were able to quantify in this work.
