| + | I would add couple of more related issues might be important for | ||
| + | the Higgs production generation: | ||
| + | |||
| + | 1. we know from the last Les Houches 2013 how big was a difference between | ||
| + | generator predictions of gg->h+2jets passing VBF h selections. The | ||
| + | proposal they made was to use in data the gluon initiated process and | ||
| + | check data with the different MC. I have discussed it a bit with | ||
| + | Frixione and looks like tt+jj with VBF selected jets may be a good | ||
| + | benchmark for Monte-Carlos. | ||
| + | |||
| + | 2. Z+b(b) production important benchmark for SUSY H+b(b). Both ATLAS and | ||
| + | CMS 8 TeV analyses see the pTZ a bit harder than LO/NLO+PS predictions | ||
| + | see slide 22 of this talk for example: | ||
| + | |||
| + | http://indico.cern.ch/event/331452/session/4/contribution/25/material/slides/1.pdf | ||
| + | |||
| + | We see with MG5_aMC@NLO that Higgs pT in H+b(b) is sensitive to the | ||
| + | shower scale. So tuning it with Z+b(b) data may help to descrive properly | ||
| + | Higgs pT in H+b(b). | ||
| + | |||
| + | **Josh** | ||
| + | CMS has produced/is producing large sets of events for ttbar+0,1,2j NLO with mg_aMC@NLO+pythia8 (FXFX merging) at both 8 and 13TeV. Since that is quite CPU intensive we can provide the lhe files if we have some common space somewhere where I can put them. | ||
