A Matrix Theory Construction of the IIA/IIB Wall / Torres, Ethan (CERN)
In this note, we give a non-perturbative construction of a lightlike domain wall separating IIA and IIB string theories in 10D in the framework of discrete light-cone quantization (DLCQ). [...]

Euclid preparation. Impact of galaxy intrinsic alignment modelling choices on Euclid 3x2pt cosmology / Euclid Collaboration
The Euclid galaxy survey will provide unprecedented constraints on cosmology, but achieving unbiased results will require an optimal characterisation and mitigation of systematic effects. [...]

Fluctuations in atom interferometers as a new tool for dark matter / Murgui, Clara (CERN) ; Plestid, Ryan (CERN)
We propose the use of the super-binomial variance in the count rate of an atom interferometer as a novel signature of dark matter. [...]

Search for massive, long-lived particles in events with displaced vertices and displaced muons in $pp$ collisions at $\sqrt{s}=13.6$ TeV with the ATLAS experiment / ATLAS Collaboration
A search is presented for massive long-lived particles in events featuring at least one displaced vertex and at least one displaced muon, using proton-proton collision data collected by the ATLAS detector at the Large Hadron Collider from 2022 to 2024 at a centre-of-mass energy of 13.6 TeV. [...]

Quantenopt. ; Munich U., ASC ; MCQST, Munich ; Kyung Hee U.) ; Grossi, Michele (CERN)
Precision measurements at electron-positron colliders provide stringent tests of the Standard Model and powerful probes of possible higher-dimensional interactions. [...]

Charmed nuclei and exotic charmed meson production at CBM@FAIR and ALICE@LHC / Chimruang, Thanaporn (Suranaree U. of Tech. ; Darmstadt, GSI) ; Herold, Christoph (Suranaree U. of Tech.) ; Limphirat, Ayut (Suranaree U. of Tech.) ; Yan, Yupeng (Suranaree U. of Tech.) ; Steinheimer, Jan (Darmstadt, GSI ; Frankfurt U.) ; Dönigus, Benjamin (Goethe U., Frankfurt (main)) ; Reichert, Tom (CERN) ; Vovchenko, Volodymyr (Houston U.) ; Bleicher, Marcus (Goethe U., Frankfurt (main) ; Helmholtz Res. Acad. Hesse for FAIR)
We make predictions for the expected multiplicities of exotic charmed hadrons and charmed nuclei in Au+Au collisions at SIS100 and LHC beam energies, using input on light hadron and charm production from the UrQMD transport model, and applying the Thermal-FIST model. [...]

Combination of ATLAS and CMS searches for Higgs boson pair production at $\sqrt{s} = 13$ TeV / ATLAS Collaboration
This Letter presents a combination of searches for Higgs boson pair (HH) production performed by the ATLAS and CMS Collaborations using proton-proton collision data sets recorded at $\sqrt{s} = 13$ TeV during the Large Hadron Collider Run 2, corresponding to integrated luminosities ranging between 126 and 140 $\mathrm{fb^{-1}}$.
