“…The leptonic vector boson decays ($\text{Z} \to \nu\nu$, $\text{W} \to \ell \nu$, and $\text{Z} \to \ell \ell$, with $\ell = e,\mu$) are considered, while the Higgs boson is reconstructed from high-momentum b quark pairs and detected as a single massive jet. …”

“…The data are used to determine 95% confidence level upper limits on the product of production cross-sections and branching fractions, σ(pp → A)·BR(A → Zh)·BR(h → bb) for mA = [200,2000] GeV assuming gluon-fusion or b-quark-associated exclusive production. Results are also interpreted in the context of benchmark models for a two-Higgs doublet extension of the Standard Model.…”

“…The data is divided into exclusive search channels characterized by the number and flavor of the leptons, the number of opposite-sign, same-flavor lepton pairs (OSSF), the invariant mass of the OSSF lepton pair, the presence or absence of hadronically decaying τ-leptons, and the number of identified bottom-quark jets. Additionally, kinematic properties of the event, such as the scalar sum of jet transverse momenta and the magnitude of the missing transverse energy in the event, are considered. …”

“…The final state probed involves the leptonic decay of a $\mathrm{Z}$ boson ($\mathrm{Z} \to \ell \ell$, with $\ell = \mathrm{e},\mu$), while the other vector boson $\mathrm{W}$ is reconstructed from high-momentum quark pairs detected as a single massive jet. The discriminating power of the jet mass distribution and jet substructure are exploited to suppress the amount of background from known standard model processes. …”

“…As a benchmark scenario, we consider the case where large-radius jets originating from a boosted Z' decay are discriminated from a background of nonresonant quark and gluon jets. We show that in the presence of systematic uncertainties on the background rate, our adversarially-trained, decorrelated tagger considerably outperforms a conventionally trained neural network, despite having a slightly worse signal-background separation power. …”

“…Studies of azimuthal anisotropies for very high $p_{T}$ particles in relativistic heavy ion collisions provide crucial information on the path length dependence of the parton energy loss mechanism in the quark-gluon plasma. Final high-precision data on the elliptic ($v_{2}$) and triangular ($v_{3}$) anisotropy harmonics of charged particles, obtained with the scalar product method, are presented up to $p_{T}$ $\sim$ 100 GeV/c in PbPb collisions at $\sqrt{s_{NN}}$ = 5.02 TeV, using data recorded during the LHC run 2 with the CMS detector. …”
