Combined searches for the production of supersymmetric top quark partners in proton-proton collisions at $\sqrt{s} = $ 13 TeV
A combination of searches for top squark pair production using proton-proton collision data at a center-of-mass energy of 13 TeV at the CERN LHC, corresponding to an integrated luminosity of 137 fb$^{-1}$ collected by the CMS experiment, is presented. [...]

Dim but not entirely dark: Extracting the Galactic Center Excess' source-count distribution with neural nets / List, Florian (Sydney U.) ; Rodd, Nicholas L. (CERN) ; Lewis, Geraint F. (Sydney U.)
The two leading hypotheses for the Galactic Center Excess (GCE) in the $\textit{Fermi}$ data are an unresolved population of faint millisecond pulsars (MSPs) and dark-matter (DM) annihilation. [...]

Simulation Study of the Observed Radio Emission of Air Showers by the IceTop Surface Extension / Coleman, Alan (Delaware U., Bartol Inst. ; CERN)
Multi-detector observations of individual air showers are critical to make significant progress to precisely determine cosmic-ray quantities such as mass and energy of individual events and thus bring us a step forward in answering the open questions in cosmic-ray physics. [...]
