Jet areas as a tool for background subtraction
In all modern hadronic colliders, jets recieve a large contribution from a soft background: pileup in the case of proton-proton collisions at the LHC, or the underlying event for heavy-ion collisions
Pileup measurement and mitigation techniques in CMS
When trying to reconstruct an event from a hard-scatter pp collision in CMS, it is of the utmost importance to correctly measure the energy from jets. The jet energy corrections (JEC) correct, on
Pileup subtraction for jet shapes.
TLDR
The method rescues the possibility of using jet shapes in the high pileup environment of current and future LHC running, as it shows with examples of quark-gluon discrimination and top tagging.
Particle-level pileup subtraction for jets and jet shapes
A bstractWe present an extension to the jet area-based pileup subtraction for both jet kinematics and jet shapes. A particle-level approach is explored whereby the jet constituents are corrected or
Performance of pile-up mitigation techniques for jets in pp collisions at √ s = 8 TeV using the ATLAS detector
The large rate of multiple simultaneous proton– proton interactions, or pile-up, generated by the Large Hadron Collider in Run 1 required the development of many new techniques to mitigate the
Recent results on jet physics from ALICE at the LHC
An overview of recent results on jet physics from the ALICE collaboration is presented. We mainly discuss azimuthal correlations and nuclear modification factors for both hadrons and jets. The very
Identification and rejection of pile-up jets at high pseudorapidity with the ATLAS detector
The rejection of forward jets originating from additional proton–proton interactions (pile-up) is crucial for a variety of physics analyses at the LHC, including Standard Model measurements and
Jet performance in CMS
The reconstruction and calibration of jets relies critically on the interplay between the tracking detectors, central calorimeters and forward calorimeters. Therefore, CMS makes use of the “Particle
Pileup mitigation at CMS in 13 TeV data
: 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
