abstract
We detail a simulation of Higgs boson production via gluon fusion, accurate at next-to-next-to-leading order in the strong coupling, including matching to a parton shower, yielding a fully exclusive, hadron-level description of the final-state. The approach relies on the POWHEG method for merging the NLO Higgs plus jet cross-section with the parton shower, and on the MINLO method to simultaneously achieve NLO accuracy for inclusive Higgs boson production. The NNLO accuracy is reached by a reweighting procedure making use of the HNNLO program.

No significant excess observed in search for SUEP signatures with muons; exclusion limits set on mediator cross section times branching fraction down to 0.05 fb at 750 GeV.
Higgs boson cross-section in H→4ℓ measured as 3.65 fb with new LHC data, consistent with SM expectation of 3.68 fb and signal strength 0.99±0.13.
Updated ATLAS search for HH → bbγγ with 308 fb⁻¹ yields observed μ_HH = 0.9^{+1.4}_{-1.1}, 95% CL limit μ_HH < 3.7, and κ_λ in [-1.6, 6.6].
Combined differential and total Higgs boson production cross sections at 13 TeV are measured and found consistent with Standard Model expectations, with a total cross section of 53.4 pb.
CMS performs a combined SMEFT fit to multiple LHC measurements and precision data, yielding individual constraints on 64 Wilson coefficients and 43 linear combinations.
Search for H->aa->4tau (4<m_a<15 GeV) with boosted di-tau reconstruction finds no excess and sets 95% CL upper limits of 0.03-0.10 on (sigma_H/sigma_SM)*BR(H->aa->4tau).
Three nonlinear interacting dark energy models with a saturation ('sparseness') scale are constrained against late-time cosmological data, showing mild preference for nonzero sparseness but no decisive improvement over ΛCDM.
No significant excess observed in CMS four-lepton data; 95% CL upper limits set on heavy scalar resonance production cross section times BR(ZZ) ranging 0.05-0.1 pb at low mass to 0 pb at high mass.
