“…The analysis focuses on the $N^0$ and $L^\pm$ decays with intermediate $W$ bosons and yielding two final-state light leptons (electron or muon) of different flavor and charge combinations, with at least two jets and large missing transverse momentum in the final state. …”

“…The first observation of the electroweak production of a W$^{+}$W$^{-}$ pair in association with two jets, with both W bosons decaying leptonically, is reported. The data sample corresponds to 138 fb$^{-1}$ of proton-proton collisions at $13$ TeV. …”

“…The search is focused on final states with three and four light leptons (electrons and muons) and large energy produced by the collision coming from all the possible decays of the heavy leptons via intermediate electroweak bosons. As no significant excesses with respect to the Standard Model predictions are observed, upper and lower limits on the production cross-section and on the heavy lepton masses are set. …”

“…Among them there is a twin-ring e⁻e⁺ collider capable to run at beam energies between 45.6 and 182.5 GeV, i.e. the energies corresponding to the resonances of the Z, W, H bosons and the top quark. The conceptual design of the two 100-km rings has advanced to what is believed to be a working solution, i.e. capability to deal with low-energy (45.6 GeV) high-current (1390 mA) version as well as the high-energy (182.5 GeV) low-current (5.4 mA) one, with intermediate energy and current steps for the other 2 resonances. …”

“…In this paper, we employ Ian Hacking’s insight that “unity” has a double meaning, singleness and harmonious integration, to revisit a major episode from the recent history of CERN: the UA1 and UA2 experiments in the early 1980s, which led to the discovery of the W and Z bosons. CERN is a complex institution, where diverse groups are called upon to cooperate. …”

“…In addition to the models previously considered, the results of the combination are interpreted in a scenario where neutralinos and charginos in a mass-degenerate higgsino triplet are produced and decay to SM bosons and a bino-like LSP. The results are consistent with expectations from the standard model. …”
