  The Standard Model of particle physics predicts the existence of quantum
tunnelling processes across topological inequivalent vacua, known as
Instantons. In the electroweak sector, instantons provide a source of baryon
asymmetry within the Standard Model. In Quantum Chromodynamics they are linked
to chiral symmetry breaking and confinement. The direct experimental
observation of Instanton-induced processes would therefore be a breakthrough in
modern particle physics. Recently, new calculations for QCD Instanton processes
in proton-proton collisions became public, suggesting sizable cross sections as
well as promising experimental signatures at the LHC. In this work, we study
possible analysis strategies to discover QCD Instanton induced processes at the
LHC and derive a first limit based on existing Minimum Bias data.
