SM Working Group: Loops, Multi-legs and Jets

List of participants (access restricted to the participants only)

TOPICS

To be updated * PDFs:

dealing with scale uncertainties in PDF fits
benchmark studies for current generation of PDFs, e.g. top distributions
dealing with tensions in LHC data, i.e. ATLAS jets vs CMS jets, top distributions
- does each group have the same reaction to the tensions?
- how to get the greatest knowledge from distributions with tensions?
electroweak effects in PDF fits
dealing with NNLO grids (NNLOJET)

Parton Showers:
- LH17 showed that PS predictions agree well with each other when input parameters are synchronized; reasonable physics choices then lead to differences; can we establish the limit of what these reasonable physics choices are?

ME+PS:
- better understanding of limits of precision for ME/ME+PS calculations
- uncertainties in matching PS with ME
- better understanding of 'reasonable' scale uncertainties at NNLO
- precision predictions in the high pT frontier

Progress with higher order calculations:
- any benchmarking, for example DY at NNLO?
- improvements for evaluation of 2→2 at NNLO
- loopedia
- outlook for 2→3 NNLO
- 3-loop, e.g. Higgs rapidity
- compact expressions at the amplitude level
- ntuples for NNLO

Jets: Where is quark/gluon discrimination useful? How does it perform? Examples:
- PDFs
- VBF
- X→gg
- Susy cascades
- ISR tagging
- W tagging
- top tagging
