We are in the middle of LHC Long Shutdown 1 (LS1). After this shutdown, Run-II will start, in which LHC will again deliver high energy particle collisions to its interaction points, but this time at higher energy and, in particular to ATLAS and CMS, at much higher luminosity.
On one hand, the higher luminosity collisions will enhance the possibilities that rare processes that we are interested in occur frequently enough for us to observe at statistically significant rates. However, on the other hand, they will also considerably increase the number of pile-up interactions, which will make the reconstruction of jets and MET greatly challenging.
While it will become more demanding to reconstruct jets and MET accurately in a high pile-up environment of Run-II, jets and MET will remain important in physics analyses. In fact, their roles will continue to expand. Jets are no longer only manifestation of light quarks and gluons but also that of boosted-heavy objects, which are resolved by the jet substructure techniques. MET is sign of neutrinos and other invisible particles, including dark matter particles, the production of which in Run-II is more seriously predicted.
This is a two-days workshop focusing on the reconstruction of jets and MET in a high pile-up environment at LHC Run-II. On the first day, experimentalists from both ATLAS and CMS and theorists together review jets and MET at Run-I and recent theoretical developments. The second day will be restricted to CMS members, in which strategy for the recommissioning of jets and MET in Run-II in CMS will be discussed.
