First TeV upper limits on the 0.1s short bursts of magnetar SGR 1935+2154 with the CTAO LST−1 /RE23/CTA-LST Collaboration
Aims. We report on the observations of the Soft Gamma Repeater (SGR) 1935+2154 performed with the Large-Sized Telescope prototype (LST−1) of the Cherenkov Telescope Array Observatory (CTAO) during periods of high-energy (HE) activity from the source. [...]

GRB 221009A: Observations with LST-1 of CTAO and implications for structured jets in long gamma-ray bursts /RE23/CTA-LST Collaboration
GRB 221009A was the brightest gamma-ray burst (GRB) observed to date. Extensive coverage of its afterglow emission across the electromagnetic spectrum was performed, providing the first strong evidence of a jet with nontrivial angular structure in a long GRB. [...]

Study of $\it{\Lambda}_{\it{b}}^\rm{0}$ and $\it{\Xi}_{\it{b}}^\rm{0}$ decays to $\it{\Lambda} h^+h^{'-}$ and evidence for $CP$ violation in $\it{\Lambda}_{\it{b}}^\rm{0}\to\it{\Lambda} K^+K^-$ decays / LHCb Collaboration
A study of $\it{\Lambda}_{\it{b}}^\rm{0}$ and $\it{\Xi}_{\it{b}}^\rm{0}$ decays to $\it{\Lambda} h^{+} h^{\prime -}$$(h^{(\prime)}=\pi, K)$ is performed using $pp$ collision data collected by the LHCb experiment during LHC Runs 1$-$2, corresponding to an integrated luminosity of $9~\rm{fb}^{-1}$.

Constraints on standard model effective field theory for a Higgs boson produced in association with W or Z bosons in the H $ \to \mathrm{b}\overline{\mathrm{b}} $ decay channel in proton-proton collisions at $ \sqrt{s} = $ 13 TeV
A standard model effective field theory (SMEFT) analysis with dimension-six operators probing nonresonant new physics effects is performed in the Higgs-strahlung process, where the Higgs boson is produced in association with a W or Z boson, in proton-proton collisions at a center-of-mass energy of 13 TeV.

Bounds on the bubble wall velocity / Ai, Wen-Yuan (King's Coll. London) ; Laurent, Benoit (McGill U., Montreal (main)) ; van de Vis, Jorinde (CERN)
Determining the bubble wall velocity in first-order phase transitions is a challenging task, requiring the solution of (coupled) equations of motion for the scalar field and Boltzmann equations for the particles in the plasma. [...]
