“…[79], a numerical extension of the MiNLO procedure to higher jet multiplicities was presented and applied to Higgs production in association with up to two jets. Most NNLO+PS applications have been done for simple 2 → 1 LHC processes or 1 → 2 decays so far, such as Higgs-boson production [75,76,80,81], Drell-Yan (DY) production [74][75][76][82][83][84], Higgsstrahlung [85][86][87], which is still a 2 → 1 process with respect to QCD corrections, and the H → b b decay [88][89][90]. There are a few notable exceptions where NNLO+PS matching was achieved for more involved colour-singlet processes, namely W + W − [91], Zγ [92], γγ [93] and ZZ [94] production.…”

We consider W+W− production in hadronic collisions and present the computation of next-to-next-to-leading order accurate predictions consistently matched to parton showers (NNLO+PS) using the MiNNLOPS method. Spin correlations, interferences and off-shell effects are included by calculating the full process pp → e+νeμ−$$ \overline{\nu} $$ ν ¯ μ. This is the first NNLO+PS calculation for W+W− production that does not require an a-posteriori multi-differential reweighting. The evaluation time of the two-loop contribution has been reduced by more than one order of magnitude through a four-dimensional cubic spline interpolation. We find good agreement with the inclusive and fiducial cross sections measured by ATLAS and CMS. Both NNLO corrections and matching to parton showers are important for an accurate simulation of the W+W− signal, and their matching provides the best description of fully exclusive W+W− events to date.

“…In recent years, there has also been much interest in the analytic resummation of double-differential observables [7][8][9][10][11] and JHEP02(2022)136 jet-related observables such as cross sections with jet vetoes [12][13][14]. Analytic higher-order resummation has also been utilized to achieve NNLO+PS matching [15][16][17][18][19][20].…”

Sudakov form factors appear ubiquitously in factorized cross sections where they allow one to resum large logarithms to all orders in perturbation theory. Their exact evaluation requires numerical integrals over anomalous dimensions, which in practice can hamper efficiency. Alternatively, one can use approximate analytic solutions, which provide fast evaluation at the cost of numerical precision and loss of properties such as renormalization group invariance. We provide an exact analytic expression of the QCD Sudakov form factor which allows one to obtain fast and numerically exact results.

We consider the Higgsstrahlung process in hadronic collisions and present the computation of next-to-next-to-leading order predictions matched to parton showers for both production and H → b b decay employing the MiNNLO PS method. We present predictions for ZH and W ± H production including spin correlations and off-shell effects by calculating the full processes ppin the narrow-width approximation for the Higgs boson. For the W ± H process, NNLO+PS accuracy in production and decay is achieved for the first time. Our calculations are validated against earlier simulations in the NNLOPS approach that includes NNLO corrections via multi-differential reweighting. The new MiNNLO PS generators for these processes, which evaluate NNLO corrections on-the-fly in the event generation, will supersede those earlier calculations. Our predictions are in good agreement with recent measurements of the Higgsstrahlung cross sections.
