Energy and coincidence-time resolution of the LaBr3:Ce-MPPC™ detectors under magnetic fields
/ Yap, Ian Chang Jie (U. Duisburg-Essen) ; Heiniger-Schell, Juliana (U. Duisburg-Essen ; CERN) ; Dang, Thien Thanh (U. Duisburg-Essen) ; De Lima, Nicole Pereira (IPEN, Sao Paulo) ; Dörschel, Björn (U. Duisburg-Essen) ; Stegenborg, Magnus Hegelund (Aalborg U.) ; dos Santos Souza, Alexandre Pinho (IPEN, Sao Paulo) ; Corrêa, Bruno Santos (IPEN, Sao Paulo ; Maraba, Para Fed. U.) ; Miranda Filho, Arnaldo Alves (IPEN, Sao Paulo) ; Gerami, Adeleh Mokhles (IPM, Tehran) et al.
Time-differential perturbed angular correlation (TDPAC) spectroscopy is a nuclear solid-state technique that requires high energy and coincidence-time resolutions from scintillation crystals and photodetectors. Traditionally, photomultiplier tubes (PMTs) have been coupled to LaBr3:Ce crystals; however, they have been replaced by Multi Pixel Photon Counters (MPPCs) for TDPAC experiments conducted under external magnetic fields.

Higgs precision at FCC-hh
/ Mastrapasqua, Paola (Louvain U., CP3)
/FCC Collaboration
The proposed hadron collider phase of the Future Circular Collider, FCC-hh, will record 30~$ab^{-1 }$ of proton-proton collisions at a center of mass energy of 85 TeV, providing an unprecedented dataset that extends both the energy and precision frontiers and enables high-statistics studies of rare processes, particularly within the Higgs sector.With billions of single-Higgs events, the FCC-hh will measure rare decays such as $H \to \mu^+\mu^-$, $H \to \gamma\gamma$, and $H \to Z\gamma$ with percent-level precision and probe the top Yukawa interaction with unmatched accuracy through $t\bar{t}H$ production. The collection of tens of millions of Higgs-pair events will allow a few-percent-level determination of the Higgs self-coupling, a key parameter for understanding electroweak symmetry breaking and vacuum stability.

Light a candle for impregnation of superconducting magnets with wax: Thermo-mechanical behavior of an alumina-filled paraffin wax from ambient to cryogenic temperatures
/ Kong, Xiang (ETH, Zurich (main)) ; Van den Eijnden, Joep L (PSI, Villigen ; ETH, Zurich (main)) ; Brem, André (PSI, Villigen) ; Araujo, Douglas (PSI, Villigen) ; Auchmann, Bernhard (PSI, Villigen ; CERN) ; Tervoort, Theo A (ETH, Zurich (main))
A paraffin-wax-based system filled with sub-micrometer alumina particles is developed for use as impregnation of superconducting magnets operating at cryogenic temperatures. The addition of alumina fillers significantly enhances the thermal and cryo-mechanical performance of the wax matrix. [...]

First-principle evaluation of inclusive hadronic $τ$ decays in QCD+QED
/ Di Carlo, Matteo (CERN) ; Bacchio, Simone (Cyprus Inst.) ; Bäske, Erik (Humboldt U., Berlin (main)) ; De Santis, Alessandro (Helmholtz Inst., Mainz ; Darmstadt, GSI) ; Evangelista, Antonio (Cyprus U.) ; Frezzotti, Roberto (INFN, Rome2 ; Rome U., Tor Vergata) ; Gagliardi, Giuseppe (INFN, Rome3) ; Holan, Lukas (Humboldt U., Berlin (main)) ; Lubicz, Vittorio (INFN, Rome3 ; Rome III U.) ; Maio, Lorenzo (INFN, Rome2 ; U. Rome 2, Tor Vergata (main)) et al.
We present a strategy to extend lattice calculations of inclusive hadronic $τ$ decays from isosymmetric QCD to QCD+QED. The inclusive decay rate can be related to suitable Euclidean correlation functions, allowing for a first-principles evaluation of electromagnetic and isospin-breaking effects. [...]

Heavy flavor spectroscopy studies at LHCb
/ Zhu, Linxuan (UCAS, Beijing)
/LHCb Collaboration
The LHCb experiment, with its exceptional vertex resolution, momentum measurement, and particle identification capabilities, has pioneered groundbreaking studies in heavy-flavour spectroscopy during Run 1 and Run 2 data-taking period. This report highlights discoveries of exotic charm-strange states and charmonia, leveraging amplitude analyses of $B\to D\bar{D}X$ and $B^+\to\psi(2S)K^{+}\pi^{+}\pi^{-}$ decays. [...]
