“…We provide a careful treatment of the contributions where either (single dissociation), both (double dissociation) or neither (elastic) proton interacts inelastically and dissociates, and interface our results to Pythia for showering and hadronization. The particle decay distribution from dissociation system, as well the survival probability for no additional proton–proton interactions, are both fully accounted for; these are essential for comparing to data where a rapidity gap veto is applied. …”

“…By combining with the LHCb measurements, which covered most of the region outside the CMS detector coverage, and some extrapolation from PYTHIA and FONLL, the total charm cross section for the full kinematic phase space is measured to be 9.40 $\pm$ 0.45 (statistical )$_{-0.95}^{+2.50}$ (FONLL/PYTHIA) mb with an extrapolation factor of 1.4 throughout all phase space. …”

“…In the context of an independent cluster model of short-range correlations, the cluster size and its decay width are extracted from the two-particle pseudorapidity correlation function and compared with previous measurements in proton-proton and proton-antiproton collisions, as well as PYTHIA predictions. The results at 0.9 TeV are in agreement with previous measurements. …”

“…Activity in the underlying event was measured with respect to the highest p_{T} track in the event. A new PYTHIA6 Monte Carlo tune, ATLAS Minimum Bias Tune 1, was produced using ATLAS minimum bias distributions measured in a diffractive limited phase-space in combination with measurements from previous hadron collider experiments. …”

“…In this project, the plausibility of measuring direct resonant s-channel Higgs production at a future high-luminosity e+e- collider machine (of the FCC-ee type) is examined. Using PYTHIA8 to generate expected samples for signal (e+e--->H-->WW*,ZZ*,bbar,gluon-gluon) and backgrounds (e+e- -->Z*,gamma*-->qqbar,tautau,WW,ZZ) in seven possible Higgs decay channels (combining isolated leptons, neutrinos and heavy-quark, light-quark and gluon jets), a total combined statistical significance of 3.6 sigma per experiment is obtained at an integrated luminosity of 10 $ab^{-1}$. …”

“…However, similar features are also seen in events simulated by the PYTHIA 8 Monash Monte Carlo generator. The simulation reveals that the observed effects result from a bias induced by the ALICE high-multiplicity trigger, which enhances the probability to have a high-$p_{\rm{T}}$ recoil jet in the forward trigger detectors and which biases towards multi-jet final states.…”
