- | * Z+bb | + | Preliminary results for Zbb production in the 5FS can be found on http://www.hep.man.ac.uk/u/graeme/public/LH_Vbb/preliminary/Zbb/ |
- | * W+bb(?) | + | * Shown are the four matching-shower combinations of Herwig7, i.e. |
+ | - NLO$\oplus$QTilde aka MCatNLO-based matching with the angular ordered shower, | ||
+ | - NLO$\oplus$Dipole aka MCatNLO-based matching with the dipole shower, | ||
+ | - NLO$\otimes$QTilde aka Powheg-based matching with the angular ordered shower, | ||
+ | - NLO$\otimes$Dipole aka Powheg-based matching with the dipole shower. | ||
+ | * The uncertainty bands are from scale variations with respect to all scales in the hard sub-processes and in the shower, i.e. muR, muF (and the corresponding scales of alpha_s and pdf arguments in the shower) and muQ (shower start scale). | ||
+ | * The central scale choice is a fixed scale (Z mass) at the moment for muR=muF=muQ. | ||
+ | * The PDF sets being used are the default PDF sets to which the showers are tuned, i.e. MMHT2014lo68cl and MMHT2014nlo68cl. | ||
+ | * Statistics: 40k, unweighted. | ||

+ | * The difference between the two is that for one we require one jet (which may contain a b quark) with a certain min pT (first link), for the other we don't cut on the b quarks at all (second link). | ||
+ | * Shown is the NLO$\oplus$QTilde aka MCatNLO-based matching with the angular ordered shower. | ||
+ | * No scale variations. | ||
+ | * The central scale choice is a fixed scale (W mass) at the moment for muR=muF=muQ. | ||
+ | * There is a choice of different PDF sets being used, i.e. | ||
+ | - MMHTnf5: MMHT2014lo68cl and MMHT2014nlo68cl, | ||
+ | - MMHTnf4: MMHT2014nlo68cl_nf4, | ||
+ | - NNPDFnf5: NNPDF30_lo_as_0118 and NNPDF30_nlo_as_0118, | ||
+ | - NNPDFnf4: NNPDF30_lo_as_0118_nf_4 and NNPDF30_nlo_as_0118_nf_4. | ||
