Hunting for QCD Instantons at the LHC in Events with Large Rapidity Gaps

We outline a strategy of how to search for QCD instantons of invariant mass 20 -- 60 GeV in diffractive events in low luminosity runs at the LHC. We show that by imposing appropriate selection criteria on the final states, one can select the kinematic regime where the instanton signal exceeds the background by a factor of at least 8. In spite of the relatively strong cuts that we impose on the total transverse energy and the number of charged tracks, \(\sum_i E_{T,i}>15\) GeV, \(N_{\rm ch}>20\) measured within the \(0
