Sub-GeV dark matter and multi-decay signatures from dark showers at beam-dump experiments / Bernreuther, Elias (UC, San Diego) ; Hemme, Nicoline (KIT, Karlsruhe, IKP ; KIT, Karlsruhe, TTP) ; Kahlhoefer, Felix (KIT, Karlsruhe) ; Kulkarni, Suchita (Graz U.) ; Ovchynnikov, Maksym (CERN)
In models of strongly-interacting dark sectors, the production of dark quarks at accelerators can give rise to dark showers with multiple dark mesons in the final state. [...]

Constrained instantons in scalar field theories / Elder, Benjamin (Imperial Coll., London) ; Gawrych, Kinga (Imperial Coll., London) ; Rajantie, Arttu (CERN ; Imperial Coll., London)
Instantons, localised saddle points of the action, play an important role in describing non-perturbative aspects of quantum field theories, for example vacuum decay or violation of conservation laws associated with anomalous symmetries. [...]

Holography of K-complexity: Switchbacks and Shockwaves / Ambrosini, Marco (U. Geneva (main)) ; Rabinovici, Eliezer (Hebrew U. ; CERN) ; Sonner, Julian (U. Geneva (main))
In this paper we study Krylov complexity in the presence of single and multiple operators in the DSSYK model, where we can use the analytical techniques coming from chord diagrammatics. [...]

NLO analysis of the subleading-power $Q_1-Q_{7\gamma}$ interference in $\bar{B}\to X_s\gamma$ at large photon energies / Bartocci, Riccardo (U. Mainz, PRISMA) ; Böer, Philipp (CERN) ; Hurth, Tobias (U. Mainz, PRISMA)
We report on progress towards including next-to-leading order (NLO) radiative corrections to the subleading-power factorization formula for the $Q_1^{q}-Q_{7γ}$ interference contribution in $\bar{B}\to X_sγ$ at large photon energies, $m_b - 2E_γ= \mathcal{O}(Λ_{\rm QCD})$. [...]

Constraints on Attractor Models of Inflation and Reheating from Planck, BICEP/Keck, ACT DR6, and SPT-3G Data / Ellis, John (King's Coll. London (main) ; CERN) ; Garcia, Marcos A.G. (UNAM, Mexico) ; Olive, Keith A. (U. Minnesota, Minneapolis (main)) ; Verner, Sarunas (U. Chicago (main))
We analyze the latest cosmic microwave background (CMB) constraints on the scalar spectral index $n_s$ and tensor-to-scalar ratio $r$ from Planck 2018, BICEP/Keck 2018, the Atacama Cosmology Telescope Data Release 6 (ACT DR6), and the South Pole Telescope (SPT-3G) data, focusing on their implications for attractor models of inflation.

Multi-Instantons, Multi-Axions, and Non-Invertible Symmetries in 4d QFT / Hong, Sungwoo (KAIST, Taejon) ; Kim, Hyungyu (KAIST, Taejon) ; Lee, Sung Mook (KAIST, Taejon ; CERN) ; Seo, Dongmin (KAIST, Taejon)
We study non-invertible global symmetries in 4d quantum field theories, aiming to generalize existing discussions to theories with multiple instantons and axions, and to make the subject more accessible to particle phenomenology. [...]

Effects of Radiative Corrections on Starobinsky Inflation / Ellis, John (King's Coll. London ; CERN) ; Gherghetta, Tony (U. Minnesota, Minneapolis (main)) ; Kaneta, Kunio (Niigata U.) ; Ke, Wenqi (U. Minnesota, Minneapolis (main)) ; Olive, Keith A. (U. Minnesota, Minneapolis (main))
We analyze radiative corrections to the Starobinsky model of inflation arising from self-interactions of the inflaton, and from its Yukawa couplings, $y$, to matter fermions, and dimensionful trilinear couplings, $κ$, to scalar fields, which could be responsible for reheating the Universe after inflation.
