TL;DR: In this article, the authors present an overview of a next-generation instrument, IceCube-Gen2, which will sharpen our understanding of the processes and environments that govern the Universe at the highest energies.

TL;DR: In this paper, the authors report constraints on the sources of ultra-high-energy cosmic rays (UHECRs) above 10^{9} GeV, based on an analysis of seven years of IceCube data.

TL;DR: In this article, a measurement of the lepton charge asymmetry in WX production at 7 TeV was presented based on data recorded by the CMS detector at the LHC and corresponding to an integrated luminosity of 36 inverse picobarns.

TL;DR: A statistical combination of several searches for the electroweak production of charginos and neutralinos is presented in this article, where a targeted analysis requiring three or more charged leptons (electrons or muons) is presented, focusing on the challenging scenario in which the difference in mass between the two least massive neutralino is approximately equal to the mass of the Z boson.

TL;DR: A search for exotic unstable neutral and charged heavy leptons was performed with the L3 detector at LEP as discussed by the authors, but no evidence for their existence was found and lower limits on their masses were set.
