“… This Note contains a detailed description of a simple nucleon coalescence model, where the phase space distributions of nucleons are generated using PYTHIA 8 with the Monash 2013 tuning. The predictions of this model can be compared to measurements of the transverse-momentum ($p_{\rm T}$) spectra and coalescence parameters $B_2$ of (anti)deuterons in pp collisions at $\sqrt{s} = $13 TeV, in and out of jets. …”

“…Here we present comparison of the background estimates as obtained with (a) complete massive matrix element for the q qbar -> W(->l nu) g*(->b bbar) process; with PYTHIA implementation of the (b) q qbar --> W process and (c) q qbar->Wg and qg->Wq processes; followed by the parton shower. …”

“…The hard process event can be completed by the initial and final state radiation, hadronisation and decays through the existing interface with either PYTHIA 6.2 or HERWIG 6.3 event generators. A distinctive feature of AcerMC is the efficient phase-space sampling, achieved by a combination of multi-channel self-optimising approach and a modified ac-VEGAS routine.…”

A distinctive feature of AcerMC is the efficient phase-space sampling, achieved by a combination of multi-channel self-optimising approach using the modified Kajantie-Byckling formalism for phase space construction and further smoothing of the phase space was obtained by using a modified ac-VEGAS algorithm.…”

“…Various measurements of $t\bar{t}$ observables, performed by the ATLAS experiment in $pp$ collisions at $\sqrt{s} = 7$ TeV, are used to constrain the initial- and final-state radiation parameters of the Pythia8 Monte Carlo. The resulting tunes are compared to previous tunes to the $Z$ boson transverse momentum at the LHC, and to the LEP event shapes in $Z$ boson hadronic decays. …”

“…We study pion production in proton–proton (pp) and in central $^{7}$Be + $^{9}$Be and $^{40}\text {Ar}+ ^{45}\text {Sc}$ collisions at CERN super proton synchrotron (SPS) energies within the Angantyr model, whose pp dynamics are modeled by PYTHIA 8.303 event generator. We have tuned the parameters of the default multi-partonic interaction (MPI) mechanism in PYTHIA 8.303 to describe simultaneously the measured rapidity and transverse momentum distributions of pions in inelastic pp-collisions in the beam momentum range from 20 to 158 GeV/c. …”
