External electron injection setup for the advanced wakefield experiment (AWAKE) run 2b
/ van Gils, N Z (U. Groningen (main) ; CERN) ; Turner, M (CERN) ; Zevi Della Porta, G (CERN ; Munich, Max Planck Inst.) ; Pannell, F (U. Coll. London) ; Bencini, V (CERN ; JAI, UK) ; Gerbershagen, A (U. Groningen (main)) ; Gschwendtner, E (CERN)
/AWAKE Collaboration
AWAKE is a plasma wakefield acceleration R&D; experiment at CERN, where wakefields are driven by relativistic and self-modulated proton bunches. The goal of AWAKE Run 2b is to demonstrate that a correctly placed plasma density step stabilises the wakefield amplitude (after saturation of self-modulation) at a higher value than without the step.

Online supernova pointing with trigger primitives in DUNE
/ Villa, Emanuele (CERN ; Geneva U.) ; Pullia, Dario (CERN)
/DUNE Collaboration
We present a fast, DAQ-level pipeline to infer the direction of a core-collapse supernova (SN)using only Trigger Primitives (TPs) in the Deep Underground Neutrino Experiment (DUNE).The approach clusters TP hits, identifies electron tracks, tags interaction channels, and regresseselectron directions with convolutional neural networks. A final sky direction is obtained bysampling a likelihood over track directions of Elastic Scattering interactions. [...]

Open-charm tetraquark states in $B\rightarrow D\bar{D}h$ decays in LHCb
/ Zhou, Tianwen (Peking U., Beijing)
/LHCb Collaboration
The study of hadronic spectroscopy provides profound insights into the dynamics of quarks and gluons, offering a deeper understanding of fundamental interactions. Notably, there is a large family of beauty hadron decay processes with similar decay topology, decaying into final states involving two open-charm hadrons, referred to as $B\to D \overline{D} h$ decays.

Muon neutrino interaction studies with SND@LHC detector
/ Paggi, Giulia (U. Bologna (main) ; INFN, Bologna)
/SND@LHC Collaboration
The Scattering and Neutrino Detector at LHC (SND@LHC) is a compact, standalone experiment located in the TI18 tunnel, 480 meters downstream of the ATLAS interaction point, designed to observe neutrinos produced in LHC proton-proton collisions. The SND@LHC detector allows for the identification of all three flavours of neutrino interactions in the pseudorapidity region $7.2 < \eta < 8.4 $ within an unexplored energy range of $100\, \rm GeV < E < 1 \,TeV$.

Flavor hierarchies with nonminimal irreducible representations
/ Banks, Hannah (Cambridge U., DAMTP ; New York U., CCPP) ; Crawford, Graeme (Glasgow U.) ; McCullough, Matthew (CERN) ; Sutherland, Dave (Glasgow U.)
We propose a new class of flavor models in which the spurion that breaks Standard Model flavor symmetries transforms in a nonminimal representation. Hierarchies in fermion masses, which arise from multiple insertions of this spurion, may be generated in a technically natural, accidental manner, from a handful of untuned O(1) elements in the UV.

Design, simulation and characterization of the ALICE ITS3 MOSS analog front-end
/ Emiliani, S (CERN) ; Kaiser, A (CERN ; U. Heidelberg (main)) ; Piro, F (CERN) ; Ripamonti, G (CERN) ; Snoeys, W (CERN) ; Villani, A (INFN, Trieste)
The upgrade of the ALICE vertex detector (ITS3) with wafer-scale stitched MAPS targets anorthogonal MIP detection efficiency > 99 %, with a fake-hit rate < 0.1 pixel$^{-1}$s$^{-1}$ and a power budget of 40 mW/cm$^{2}$. The MOSSwafer-scale monolithic sensor analog front-end, featuring ∼ 0.55mV/e$^{-}$ gainand < 15 e$^{-}$ rms noise and threshold dispersion each, was designed, prototyped andmeasured, confirming these performance targets.

Operational deployment of high brightness LHC beams in the SPS
/ Li, Kevin (U. Rome La Sapienza (main) ; CERN) ; Zannini, Carlo (U. Rome La Sapienza (main) ; CERN) ; Rumolo, Giovanni (U. Rome La Sapienza (main) ; CERN) ; Papotti, Giulia (U.

Rome La Sapienza (main) ; CERN) ; Paraschou, Konstantinos (U. Rome La Sapienza (main) ; CERN) ; Schenk, Michael (U. Rome La Sapienza (main) ; CERN)
Following the LHC Injector Upgrade programme (LIU) there has been a gradual ramp-up of the intensity of LHC beams in the CERN Super Proton Synchrotron (SPS). This was initially hampered by vacuum issues in several critical components, such as RF cavities and kicker magnets, requiring extensive scrubbing campaigns to condition these components. [...]
