Search for a new heavy scalar resonance decaying to a pair of Z bosons in the four-lepton final state in proton-proton collisions at $ \sqrt{s} = $ 13 TeV
A search for a new heavy scalar resonance decaying to two Z bosons, each subsequently decaying to a pair of electrons or muons, is presented. [...]

Studies of $ \mathrm{Z} \to 4\ell $ decays in proton-proton collisions at $ \sqrt{s} = $ 8 and 13 TeV
Decays of Z bosons to four charged leptons (electrons and muons) are studied in proton-proton collisions at $ \sqrt{s} = $ 8 and 13 TeV. [...]

Associated $Z$ + $J/\psi$ production as a probe of multiparton interactions in the forward region / LHCb Collaboration
This letter reports a study of associated $Z$ boson and prompt $J/ψ$ production in proton-proton collisions at $\sqrt{s}=13$ TeV with the LHCb detector in the forward rapidity region, using a data sample taken during 2016 to 2018 corresponding to an integrated luminosity of $5.1 \mathrm{fb}^{-1}$.

Scalar memory from compact binary coalescences / Zosso, Jann (Bohr Inst.) ; Gasparotto, Silvia (CERN) ; Aresté Saló, Llibert (Leuven U.) ; Doneva, Daniela D. (U. Valencia (main) ; U. Tubingen) ; Yazadjiev, Stoytcho S. (Sofiya U. ; Sofiya, Inst. Math.)
Gravitational memory provides a distinctive low-frequency probe of gravity, but explicit merger studies beyond general relativity remain limited. [...]

We present Archi, an open-source, end-to-end framework for scientific collaborations that combines the systematic ingestion and organization of heterogeneous data sources with the deployment of configurable, private, and extensible agents that retrieve and reason over them. [...]

Stochastic Dynamics of Heavy Quarks in Strongly Coupled Plasma / Rajagopal, Krishna (MIT) ; Scheihing-Hitschfeld, Bruno (UC, Santa Barbara (main)) ; Wiedemann, Urs Achim (CERN)
We study the stochastic dynamics of heavy quarks propagating through the strongly coupled plasma of $\mathcal{N}=4$ supersymmetric Yang-Mills (SYM) theory at nonzero temperature in terms of the corresponding Kolmogorov equation, which correctly describes their kinetic equilibration and the non-Gaussian fluctuations in their momenta without having to restrict their velocity to the non-relativistic regime.

Yoctosecond imaging of the ground state of $^{129}$Xe at the Large Hadron Collider / Giacalone, Giuliano (CERN) ; Nijs, Govert (CERN) ; van der Schee, Wilke (CERN ; Utrecht U. ; NIKHEF, Amsterdam)
Imaging a quantum many-body system requires probes that resolve the coordinates of its constituents in sufficiently large event samples, allowing measurements of correlation functions [1-4]. [...]

The decay rate of metastable cosmic strings beyond the thin-string approximation / Domcke, Valerie (CERN) ; Hamada, Yu (Osaka U.)
In the context of grand unified theories, any cosmic strings present in the post-inflationary universe are likely to be metastable, with a decay rate set by the spontaneous creation of monopole pairs on the string. [...]
