abstract
The aim of this work is to describe in detail the POWHEG method, first suggested by one of the authors, for interfacing parton-shower generators with NLO QCD computations. We describe the method in its full generality, and then specify its features in two subtraction frameworks for NLO calculations: the Catani-Seymour and the Frixione-Kunszt-Signer approach. Two examples are discussed in detail in both approaches: the production of hadrons in e+e- collisions, and the Drell-Yan vector-boson production in hadronic collisions.

ATLAS reports an 8+ sigma excess in ttbar production near threshold, consistent with NRQCD quasi-bound states and measuring 9.3 pb.
First differential measurement of muon neutrino-nucleon cross section and flux in six TeV-scale energy bins using FASER at the LHC, with results consistent with Standard Model expectations.
NNLO+PS matching for gluon-fusion Higgs pair production is implemented in MiNNLOPS with approximate top-mass effects, validated against fixed-order NNLO and compared to GENEVA, with results for decay channels and trilinear coupling variations.
CMS measures Υ(1S,2S,3S) → τ⁺τ⁻ with 5.8σ significance and cross section 3.5 ± 0.7 (stat) ± 0.7 (syst) nb while setting 95% CL upper limits of 40-400 pb on spin-zero resonance production to ττ with no observed excess in 61.9 fb⁻¹ of 13.6 TeV data.
A resonance-sensitive metric using relative transverse momenta allows cell resampling to reduce negative weights in NLO W+2jets samples while preserving resonance predictions with high accuracy.
A multiplicative matching scheme reweights Born-level events in PYTHIA 8 so the first parton shower emission follows the real NLO matrix element, improving agreement with HERA DIS data.
CMS reports a simultaneous measurement of 25 N-subjettiness observables in 1-, 2-, and 3-prong jets, unfolded to stable particles with particle-level correlations for QCD modeling.
First evidence for ZZ gamma production at 3.7 sigma and observation of 4 lepton gamma at 5.0 sigma in CMS data at 13 TeV, with measured fiducial cross sections consistent with predictions.
