Article Synopsis
- The study focuses on detecting multijet signatures from proton-proton collisions at a high energy of 13 TeV, analyzing a dataset totaling 128 fb^{-1}.
- A special data scouting method is utilized to pick out events with low combined momentum in jets.
- This research is pioneering in its investigation of electroweak particle production in R-parity violating supersymmetric models, particularly examining hadronically decaying mass-degenerate higgsinos, and it broadens the limits on the existence of R-parity violating top squarks and gluinos.
The first search for soft unclustered energy patterns (SUEPs) is performed using an integrated luminosity of 138 fb^{-1} of proton-proton collision data at sqrt[s]=13 TeV, collected in 2016-2018 by the CMS detector at the LHC. Such SUEPs are predicted by hidden valley models with a new, confining force with a large 't Hooft coupling. In events with boosted topologies, selected by high-threshold hadronic triggers, the multiplicity and sphericity of clustered tracks are used to reject the background from standard model quantum chromodynamics.

- - The experiment at Lawrence Berkeley National Laboratory aimed to produce a superheavy element with an atomic number of 114 or greater by bombarding an actinide target with a ^{50}Ti beam.
- - Using the Berkeley Gas-filled Separator, researchers successfully isolated and implanted produced Livermorium (Lv) ions into a high-tech detector system, observing two decay chains linked to ^{290}Lv.
- - The measured production cross-section of the process was 0.44 picobarns at a specific energy, marking the first published evidence of superheavy element production near the "island of stability" with this method, paving the way for future discoveries beyond element Z=118.
The first search for the Z boson decay to ττμμ at the CERN LHC is presented, based on data collected by the CMS experiment at the LHC in proton-proton collisions at a center-of-mass energy of 13 TeV and corresponding to an integrated luminosity of 138 fb^{-1}. The data are compatible with the predicted background. For the first time, an upper limit at the 95% confidence level of 6.

Methods: This retrospective, multicentre study included ulcerative colitis patients with ileal pouch construction and were later diagnosed with an inflammatory pouch disorder between 1995 and 2020. Classifications, behaviour and therapies applied were recorded and compared in the long-term.
