Pileup is one of the limiting factors in many LHC studies and the experiments’ ability to control its adverse effects can even affect decisions on machine running.
The purpose of this workshop is to bring together the community of people with experience in pileup mitigation at the LHC, in order to foster exchanges on a range of new ideas that are currently emerging in the field.
Topics to be covered include
generic jet use, i.e. correcting jet transverse momenta and suppression of pileup jets
advanced jet use, correcting shapes and masses and groomers/taggers
questions such as whether to correct whole jet observables (pt, mass), the particle within a jet, or even attempt event-wide PU correction
interplay of these questions with different experimental jet reconstruction methods (detector effects, topoclustering and particle flow, detector noise suppression, etc.)
pileup in contexts beyond jets, such as lepton & photon isolation and missing transverse energy measurements
how best to perform comparisons between different experiments and with theorists’ studies
The workshop will include ample hands-on sessions for trying out and sharing PU mitigation code and results, using standalone simulations and code.
It will run over a long weekend, from the morning of Friday May 16th until late afternoon on Sunday May 18th.
