Single-photon loading of polar molecules into an optical trap / Schellenberg, Bart J (Nikhef, Amsterdam ; U. Groningen (main)) ; Prinsen, Eifion H (Nikhef, Amsterdam ; U. Groningen (main)) ; Nauta, Janko (CERN) ; Pašteka, Lukáš F (U. Groningen (main) ; Nikhef, Amsterdam ; Comenius U.) ; Borschevsky, Anastasia (U. Groningen (main) ; Nikhef, Amsterdam) ; Hoekstra, Steven (U. Groningen (main) ; Nikhef, Amsterdam)
We propose a scheme to transfer molecules from a slow beam into an optical trap using only a single photon absorption and emission cycle. [...]

Superradiance Constraints from GW231123 / Caputo, Andrea (CERN ; U. Rome La Sapienza (main) ; INFN, Rome) ; Franciolini, Gabriele (CERN) ; Witte, Samuel J. (Oxford U., Theor. Phys. ; DESY ; Hamburg U., Inst. Theor. Phys. II)
Gravitational wave observations have recently revealed with high significance, and high precision, the existence of $\mathcal{O}(100) \, M_\odot$ rapidly rotating black holes, allowing gravitational wave events to be used for the first time to probe unexplored axion parameter space using the phenomenon known as black hole superradiance. [...]

Ultra High Energy Neutrino Event KM3-230213A as a Signal of Electroweak Vacuum Turbulence in Merging Black Hole Binaries / Sakharov, Alexander S. (Manhattan Coll., Riverdale ; CERN) ; Konoplich, Rostislav (Manhattan Coll., Riverdale ; New York U.) ; Gogberashvili, Merab (Javakhishvili State U. ; Tbilisi, Inst. Phys.)
The recent detection of the ultra-high-energy neutrino event KM3-230213A ($\sim$220 PeV) by KM3NeT telescope poses a challenge to conventional astrophysical models, particularly in light of the absence of similar $\gtrsim$100 PeV events in IceCube data, despite its larger exposure. [...]

(Virginia Tech.) ; Tabrizi, Zahra (Pittsburgh U. ; CERN) ; Thompson, Adrian (Texas A-M ; Northwestern U.) ; Yu, Jaehoon (Texas U., Arlington)
In this work, motivated by several beyond the Standard Model signal topologies, we perform detailed background mitigation analyses for the DUNE near detector. [...]

Search for the decay $B^0 \rightarrow \phi\phi$ / LHCb Collaboration
A search for the decay $B^0 \rightarrow ϕϕ$ is made using $pp$ collision data collected with the LHCb detector at centre-of-mass energies of 7, 8 and 13 TeV, corresponding to an integrated luminosity of $9$ fb$^{-1}$. [...]
