Measurements of the properties of the Higgs-like boson in the four lepton decay channel with the ATLAS detector using 25 fb$^{-1}$ of proton-proton collision data (2013, methodology): “3 Signal and Background Simulation The H → ZZ(∗) → 4` signal is modelled using the P Monte Carlo (MC) event generator [11, 12], which calculates separately the gluon fusion (ggF) and vector-boson fusion (VBF) production mechanisms with matrix elements up to next-to-leading order (NLO).”
Search for a Higgs boson in the mass range from 145 to 1000 GeV decaying to a pair of W or Z bosons (2015, methodology): “Within the solenoid volume are a silicon pixel and strip tracker, a lead tungstate crystal electromagnetic calorimeter (ECAL), and a brass and scintillator hadron calorimeter, each composed of a barrel and two endcap sections.”
Higgs Physics at the HL-LHC and HE-LHC (2019, background): “In order to connect these calculations to experimental measurements one would ideally need merged 2- and 3-jet NLO samples matched with the parton shower [81, 82] (NLOPS level) or even better a fully exclusive generator for VBF matched with the parton shower at NNLO (NNLOPS) .”
A general framework for implementing NLO calculations in shower Monte Carlo programs: the POWHEG BOX (2010, methodology): “Until now, the POWHEGmethod has been applied to the following processes: Z pair hadroproduction [3], heavy-flavour production [4], e+e− annihilation into hadrons [5] and into top pairs [6], Drell-Yan vector boson production [7, 8], W ′ production [9], Higgs boson production via gluon fusion [10, 11]”

Single-top Wt-channel production matched with parton showers using the POWHEG method (2010, background): “We also stress that, in POWHEG, Wt-channel was the missing process among the ones relevant for H → WW searches: Higgs production via gluon [37] and vector-boson fusion [42] are already available, as well as tt̄ [33] and V V [66] production, which (together with single-top Wt) are the main background”
Search for electroweak production of supersymmetric states in scenarios with compressed mass spectra at √s = 13 TeV with the ATLAS detector (2017, unknown): “POWHEG - BOX v1 and v2 [78 – 80] interfaced to PYTHIA 6.428 with the PERUGIA 2012 tune [81] were used to simulate t ¯ t and single-top production at NLO in the matrix element.”
Handbook of LHC Higgs Cross Sections: 1. Inclusive Observables (2011, methodology): “The showerMonte Carlo’s (MC@NLO and HERWIG) both resum these logarithms at the NLL level, and in the NNLO result one more logarithmic term is included in the cross section with respect to the NLO one.”
