The Simplest $B$ Decay, Precisely / Cornella, Claudia (CERN) ; Ferré, Max (U. Mainz, PRISMA) ; König, Matthias (U. Mainz, PRISMA) ; Neubert, Matthias (U. Mainz, PRISMA ; Cornell U., LEPP)
We derive the QCD$\times$QED factorization theorem governing the leptonic decay $B^-\toμ^-\barν_μ(γ)$ at all orders in $α_s$ and $α$. [...]

Top quark FCNC in Randall-Sundrum models: post-LHC allowed rates and searches at $e^+e^-$ and $μ^+ μ^-$ colliders / Airen, Sagar (Maryland U.) ; Franceschini, Roberto (INFN, Rome3 ; Rome III U. ; CERN)
We present the sensitivity to Flavor Changing Neutral Currents (FCNC) in interactions involving the top quark at future $e^+e^-$ and $μ^+μ^-$ machines. [...]

Resonant Landau-Zener conversion in multi-axion systems / Dunsky, David I. (New York U., CCPP) ; Manzari, Claudio Andrea (UC, Berkeley ; LBL, Berkeley) ; Quílez, Pablo (UC, San Diego ; CERN) ; Ramos, Maria (CERN) ; Sørensen, Philip (U. Padua, Dept. Phys. Astron. ; INFN, Padua)
Multiple axions may emerge in the low-energy effective theory of Nature. Generically, the potentials describing these axion fields are non-diagonal, leading to mass mixing between axion states which can be temperature-dependent due to QCD instanton effects. [...]

A cosmologist's take on Little Red Dots / De Luca, Valerio (Johns Hopkins U.) ; Del Grosso, Loris (Johns Hopkins U.) ; Franciolini, Gabriele (Padua U. ; INFN, Padua ; CERN) ; Kritos, Konstantinos (Johns Hopkins U.) ; Berti, Emanuele (Johns Hopkins U.) ; D'Orazio, Daniel (Johns Hopkins U. ; Baltimore, Space Telescope Sci. ; Bohr Inst.) ; Silk, Joseph (Johns Hopkins U. ; Paris, Inst. Astrophys. ; Oxford U.)
The James Webb Space Telescope (JWST) has uncovered a population of compact, high-redshift sources, the Little Red Dots (LRDs), which may host supermassive black holes (BHs) significantly heavier than their stellar content compared with local scaling relations. [...]

$Λ_b \to Λ$ Form Factors from Light-Cone Sum Rules with $Λ$-Baryon Distribution Amplitudes / Mahmoudi, F. (IP2I, Lyon ; CERN ; IUF, Paris) ; Mishra, D. (IP2I, Lyon)
We compute the $Λ_b \to Λ$ transition form factors using light-cone sum rules based on $Λ$-baryon distribution amplitudes, including contributions up to twist--6. [...]
