 +**__Techniques and calculations for SM phenomenology:​__**
 +
 +` *  Calculations: ​
 +    * expected precision for fundamental Standard Model processes at 14 and 100 TeV; what calculations are needed to match this precision?
 +    * 2->3 at NNLO; status/​challenges/​prospects
 +    * theory uncertainties;​ more rigorous estimates? correlations?​
 +    * theoretically sound definition of FONLL at the differential level, beyond incl. cross sections?
 +
 +  * PDFs: 
 +    * followup on PDF4LHC15 benchmarking exercise; better understanding of tolerances, tensions
 +    * EW corrections/​EW PDFs; how to provide consistent calculations
 +    * small x resummation;​ what is HERA trying to tell us? 
 +    * EIC; what will EIC tell us? how do we prepare for that?
 +
 +
 +  * Higgs: ​
 +    * understanding the SM for high Higgs pT; role of top mass corrections/​scheme (MSbar vs on-shell); improving channel sensitivities
 +    * polarisation measurements (for diboson/VBS as well)
 +
 +
 +  * Top: 
 +    * MSbar vs on-shell
 +    * ttW; tension; can new calculations resolve it? 
 +
 +
