With increasing instantaneous luminosity at the LHC come additional reconstruction challenges.At high luminosity, many collisions occur simultaneously within one proton-proton bunch crossing.The isolation of an interesting collision from the additional "pileup" collisions is needed for effective physics performance.In the CMS Collaboration, several …

Machine-learning (ML) techniques are explored to identify and classify hadronic decays of highly Lorentz-boosted W/Z/Higgs bosons and top quarks.Techniques without ML have also been evaluated and are included for comparison.The identification performances of a variety of algorithms are characterized in simulated events …

Methods are presented for calibrating the hadron calorimeter system of the CMS detector at the LHC. The hadron calorimeters of the CMS experiment are sampling calorimeters of brass and scintillator, and are in the form of one central detector and two endcaps. …
