CMS results on dark QCD signatures (emerging jets, semivisible jets, SUEP) / Cazzaniga, Cesare Tiziano (Zurich, ETH) /CMS Collaboration
We present recent results from the CMS experiment on searches for strongly coupled dark sectors using data collected during LHC Run 2. Such models can give rise to unconventional final states that may evade traditional LHC searches, including jets with unusual substructure, events with high multiplicities of soft, spherically distributed particles, or multiple displaced vertices.This report focuses on the latter two scenarios. [...]

Recent results on searches with boosted Higgs bosons at CMS / Mokhtar, Farouk (UC, San Diego) /CMS Collaboration
The study of boosted Higgs bosons at the LHC provides a unique window to probe Higgs boson couplings at high energy scales and search for signs of physics beyond the standard model. In these proceedings, we present recent results on boosted Higgs boson searches at the CMS experiment, highlighting innovative reconstruction and tagging techniques that enhance sensitivity in this challenging regime..

Evidence of medium response to hard probes using correlations of Z bosons with hadrons in heavy ion collisions
The first measurement of pseudorapidity and azimuthal angle distributions relative to the momentum vector of a Z boson for low transverse momentum ($ p_{\mathrm{T}} $) charged hadrons in lead-lead (PbPb) collisions is presented. [...]

A Prototype Hybrid Mode Cavity for Heterodyne Axion Detection / Li, Zenghai (SLAC) ; Zhou, Kevin (UC, Berkeley ; LBL, Berkeley) ; Oriunno, Marco (SLAC) ; Berlin, Asher (Fermilab) ; Calatroni, Sergio (CERN) ; D'Agnolo, Raffaele Tito (IPhT, Saclay ; LPENS, Paris) ; Ellis, Sebastian A.R. (Geneva U., CAP ; Geneva U., Dept. Theor. Phys.) ; Schuster, Philip (SLAC) ; Tantawi, Sami G. (SLAC ; Arizona State U.) ; Toro, Natalia (SLAC)
In the heterodyne approach to axion detection, axion dark matter induces transitions between two modes of a microwave cavity, resulting in a parametrically enhanced signal power. [...]

A method for correcting the substructure of multiprong jets using the Lund jet plane / CMS Collaboration
Many analyses at the CERN LHC exploit the substructure of jets to identify heavy resonances produced with high momenta that decay into multiple quarks and/or gluons. [...]

Krylov Complexity / Rabinovici, Eliezer ; Sánchez-Garrido, Adrián ; Shir, Ruth ; Sonner, Julian
We introduce and review a new complexity measure, called `Krylov complexity', which takes its origins in the field of quantum-chaotic dynamics, serving as a canonical measure of operator growth and spreading. [...]
