Search for dark matter produced in association with a Higgs boson decaying to bottom quarks in proton-proton collisions at $ \sqrt{s} = $ 13 TeV
A search for dark matter particles produced in association with a Higgs boson decaying to a bottom quark-antiquark pair in proton-proton collisions at $ \sqrt{s}= $ 13 TeV is presented. [...]

Reconstruction of atmospheric neutrinos in DUNE's horizontal-drift far-detector module / DUNE Collaboration
This paper reports on the capabilities in reconstructing and identifying atmospheric neutrino interactions in one of the Deep Underground Neutrino Experiment's (DUNE) far detector modules, a liquid argon time projection chamber (LArTPC) with horizontal drift (FD-HD) of ionization electrons. [...]

A cosmologist's take on Little Red Dots / De Luca, Valerio ; Del Grosso, Loris ; Franciolini, Gabriele ; Kritos, Konstantinos ; Berti, Emanuele ; D'Orazio, Daniel ; Silk, Joseph
The James Webb Space Telescope (JWST) has uncovered a population of compact, high-redshift sources, the Little Red Dots (LRDs), which may host supermassive black holes (BHs) significantly heavier than their stellar content compared with local scaling relations. [...]

First comments on a descoped/staged FCC-ee / Blondel, Alain (LPNHE, Paris) ; Grojean, Christophe (DESY ; Humboldt U., Berlin) ; Janot, Patrick (CERN) ; Wilkinson, Guy (Oxford U.)
In response to its remit, the European Strategy Group (ESG) recommended the electron-positron Future Circular Collider (FCC-ee) as the preferred option for the next flagship collider at CERN; and a descoped FCC-ee as the preferred alternative option (with reduced synchrotron radiation (SR) power, without a run at the $\rm t \bar t$ threshold, and with only two interaction regions) in the event that the preferred option turns out not to be feasible.
