Issues in jet physics:Session
I
G. Salam
and M. Wobisch(Conveners)
The topics that will be addressed by the
working group will be
- Identification and study of benchmark channels, such as dijet events,
ttbar, Zprime, W+jets, boosted heavy-particle decays, and some BSM processes.
- Quantitative measures of jet finder performance and robustness, dependence
(e.g.) on Pt, and related optimizations
- Theoretical aspects of jet finders: IR and collinear safety properties
of current algorithms, proposals of new algorithms, new ways of using
existing algorithms
- Impact of non-perturbative contributions to jets (hadronisation, underlying
event, pileup) and correction methods.
- Lessons from jet-finding at the Tevatron
- Detector related jet issues: ATLAS/CMS comparison (particle and detector
level, with or without magnetic field), independence of results on detector
geometry.
- Provide some event-by-event comparison between algorithms to illustrate
what we've learnt from the above quantitative studies.
- Flavour of jets (both heavy-flavour and light-quark v. gluon), examining theoretical techniques and experimental feasibility.
The aim of these studies is to reach a "Les Houches proposal"
for jet-finding at the LHC. It should balance performance, robustness
and flexibility across the range of benchmark channels, with perhaps different
jet-finding solutions according to the particular task.
