“…8 predictions obtained with MCatNLO+PYTHIA8 are compared with MCatNLO+CAS3. In the calculation of MCatNLO+PYTHIA8, the PYTHIA8 subtraction terms are used and the NNPDF3.0 [68] parton density and tune CUETP8M1 [69] are applied. The uncertainties of the PYTHIA prediction are derived by combining the fixed-order scale variation from MCatNLO with renormalization scale variations in the parton shower.…”

The azimuthal correlation, ∆φ 12 , of high transverse momentum jets in collisions at √ s = 13 TeV is studied by applying PB-TMD distributions to NLO calculations via MCatNLO together with the PB-TMD parton shower. A very good description of the cross section as a function of ∆φ 12 is observed. In the back-to-back region of ∆φ 12 → π, a very good agreement is observed with the PB-TMD Set 2 distributions while significant deviations are obtained with the PB-TMD Set 1 distributions. Set 1 uses the evolution scale while Set 2 uses transverse momentum as an argument in α s , and the above observation therefore confirms the importance of an appropriate soft-gluon coupling in angular ordered parton evolution. The total uncertainties of the predictions are dominated by the scale uncertainties of the matrix element, while the uncertainties coming from the PB-TMDs and the corresponding PB-TMD shower are very small. The ∆φ 12 measurements are also compared with predictions using MCatNLO together PYTHIA8, illustrating the importance of details of the parton shower evolution.

“…The samples produced by MadGraph and POWHEG are generated with the NNPDF3.0 set of parton distribution functions, while the samples produced by PYTHIA use the NNPDF2.3LO set [69,70,71]. Parton shower and hadronization processes are modelled using the generator PYTHIA with the tune CUETP8M1 [72]. The latter is based on the Monash tune [73].…”

We present an algorithm for the reconstruction of the Higgs mass in events with Higgs bosons decaying into a pair of τ leptons. The algorithm is based on matrix element (ME) techniques and achieves a relative resolution on the Higgs boson mass of typically 15-20%. A previous version of the algorithm has been used in analyses of Higgs boson production performed by the CMS collaboration during LHC Run 1. The algorithm is described in detail and its performance on simulated events is assessed. The development of techniques to handle τ decays in the ME formalism represents an important result of this paper.

“…The EPOS MC generator, specialised for simulation of inclusive soft QCD processes, displays particularly discrepant features as the p lead T scale increases, casting doubt on its suitability for modelling LHC multiple pp interactions despite currently providing the best description of minimum-bias data. Further information about MC generator tunes can be found in [9]. ALICE Collaboration presented the first observation of strangeness enhancement in high-multiplicity pp collisions [10].…”
