Thermal Stress Tensor Correlators near Lightcone and Holography / Esper, Chantelle (Hamilton Math. Inst., Dublin) ; Huang, Kuo-Wei (Hamilton Math. Inst., Dublin) ; Karlsson, Robin (CERN) ; Parnachev, Andrei (Hamilton Math. Inst., Dublin) ; Valach, Samuel (Hamilton Math. Inst., Dublin)
We consider thermal stress-tensor two-point functions in holographic theories in the near-lightcone regime and analyse them using the operator product expansion (OPE). [...]

A new source for light dark matter isocurvature in low scale inflation / Caputo, Andrea (CERN) ; Geller, Michael ; Rossi, Giuseppe
Light scalar and pseudoscalar particles are compelling dark matter candidates, with a vast running experimental program to discover them. [...]

Large Charge 't Hooft Limit of $\mathcal{N}=4$ Super-Yang-Mills / Caetano, João (CERN) ; Komatsu, Shota (CERN) ; Wang, Yifan (New York U., CCPP)
The planar integrability of $\mathcal{N}=4$ super-Yang-Mills (SYM) is the cornerstone for numerous exact observables. [...]

Composing arbitrarily many $SU(N)$ fundamentals / Polychronakos, Alexios P. (City Coll., N.Y. ; CUNY, Graduate School - U. Ctr.) ; Sfetsos, Konstantinos (Athens U. ; CERN)
We compute the multiplicity of the irreducible representations in the decomposition of the tensor product of an arbitrary number $n$ of fundamental representations of $SU(N)$, and we identify a duality in the representation content of this decomposition. [...]

Limits from the grave: resurrecting Hitomi for decaying dark matter and forecasting leading sensitivity for XRISM / Dessert, Christopher (New York U., CCPP ; Flatiron Inst., New York) ; Ning, Orion ; Rodd, Nicholas L. ; Safdi, Benjamin R.
The Hitomi X-ray satellite mission carried unique high-resolution spectrometers that were set to revolutionize the search for sterile neutrino dark matter (DM) by looking for narrow X-ray lines arising from DM decays. [...]

Resurgent Asymptotics of Jackiw-Teitelboim Gravity and the Nonperturbative Topological Recursion / Eynard, Bertrand (IPhT, Saclay ; Stanford U., ITP ; Stanford U., Phys. Dept.) ; Garcia-Failde, Elba (Paris, LPTHE) ; Gregori, Paolo (IPhT, Saclay ; Stanford U., ITP ; Stanford U., Phys. Dept. ; Lisbon, IST Maths) ; Lewanski, Danilo (Zurich U., Inst. Math. ; Trieste U.) ; Schiappa, Ricardo (Lisbon, IST Maths)
Jackiw-Teitelboim dilaton-quantum-gravity localizes on a double-scaled random-matrix model, whose perturbative free energy is an asymptotic series. [...]

Two-Loop QCD Corrections for Three-Photon Production at Hadron Colliders / Abreu, Samuel (CERN ; U. Edinburgh, Higgs Ctr. Theor. Phys.) ; De Laurentis, Giuseppe ; Ita, Harald ; Klinkert, Maximillian ; Page, Ben (CERN) ; Sotnikov, Vasily (Zurich U. ; Michigan State U.)
We complete the computation of the two-loop helicity amplitudes for the production of three photons at hadron colliders, including all contributions beyond the leading-color approximation. [...]

Dark Sectors with Mass Thresholds Face Cosmological Datasets / Allali, Itamar J. (Tufts U.) ; Rompineve, Fabrizio (CERN ; Barcelona, IFAE ; Barcelona, Autonoma U.) ; Hertzberg, Mark P. (Tufts U.)
Interacting dark sectors may undergo changes in the number of their relativistic species during the early universe, due to a mass threshold $m$ (similar to changes in the Standard Model bath), and in doing so affect the cosmic history. [...]

Electroweak Loop Contributions to the Direct Detection of Wino Dark Matter / Ellis, John (King's Coll. London ; CERN) ; Nagata, Natsumi ; Olive, Keith A. (Minnesota U.) ; Zheng, Jiaming
Electroweak loop corrections to the matrix elements for the spin-independent scattering of cold dark matter particles on nuclei are generally small, typically below the uncertainty in the local density of cold dark matter. [...]

Thick Wall from Thin Walls / Espinosa, J.R. (Madrid, IFT ; CERN)
An Euclidean bounce describing vacuum decay can be considered as an infinite stack of concentric thin shells to which a thin-wall action can be assigned. [...]
