FLAG Review 2024 / Flavour Lattice Averaging Group (FLAG) Collaboration
We review lattice results related to pion, kaon, $D$-meson, $B$-meson, and nucleon physics with the aim of making them easily accessible to the nuclear and particle physics communities. [...]

Nailing down the theoretical uncertainties of $\overline{\rm D}$ spectrum produced from dark matter / Di Mauro, Mattia (INFN, Turin) ; Fornengo, Nicolao (Turin U.) ; Jueid, Adil (IBS, Daejeon, CTPU) ; de Austri, Roberto Ruiz (Valencia U., IFIC) ; Bellini, Francesca (INFN, Bologna)
The detection of cosmic antideuterons ($\overline{\rm D}$) at kinetic energies below a few GeV/n could provide a smoking gun signature for dark matter (DM). [...]

Photon production in top quark events at ATLAS and CMS / Ribeiro Lopes, Beatriz (CERN) /ATLAS and CMS Collaborations
Top quark production in association with a photon offers a unique test ground for the standard model predictions, as it is sensitive to the top-photon coupling. These processes are rare when compared to standard top pair production, however the large amounts of data delivered by the LHC open the window to precise measurements. [...]

Design of a Level-1 Long-Lived Particle Trigger in the CMS Hadron Calorimeter / Kopp, Gillian Baron (Princeton U.) ; Tully, Christopher (Princeton U.) ; Chung, Wonyong Paul (Princeton U.) ; Kennedy, Kiley Elizabeth (Princeton U.) ; Hoienko, Svitlana (Princeton U.) ; Mans, Jeremiah Michael (Minnesota U.) ; Krohn, Michael David (Minnesota U.) ; Crossman, Bryan James (Minnesota U.) ; Hiltbrand, Joshua (Baylor U.) ; Skuja, Andris (Maryland U.) et al.
The Hadron Calorimeter (HCAL) in the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider (LHC) was recently upgraded for Run 3 to introduce depth segmentation and online timing measurements, expanding the physics capabilities. In particular, the augmentation of the calorimeter information at the hardware trigger level enables quick identification and recording of long-lived particle decays using lower thresholds on energy-based event quantities. [...]

Run 3 performance and advances in heavy-flavor jet tagging in CMS / Sarkar, Uttiya (Aachen, Tech. Hochsch.) /CMS Collaboration
Identification of hadronic jets originating from heavy-flavor quarks is extremely important to several physics analyses in High Energy Physics, such as studies of the properties of the top quark and the Higgs boson, and searches for new physics. Recent algorithms used in the CMS experiment were developed using state-of-the-art machine-learning techniques to distinguish jets emerging from the decay of heavy flavour (charm and bottom) quarks from those arising from light-flavor (udsg) ones.

Ultra-Slow-Roll Inflation on the Lattice: Backreaction and Nonlinear Effects / Caravano, Angelo (Paris, Inst. Astrophys.) ; Franciolini, Gabriele (CERN) ; Renaux-Petel, Sébastien (Paris, Inst. Astrophys.)
Violating the slow-roll regime during the final stages of inflation can significantly enhance curvature perturbations, a scenario often invoked in models producing primordial black holes and small-scale scalar induced gravitational waves. [...]
