Evidence for longitudinally polarized $W$ bosons in the electroweak production of same-sign $W$ boson pairs in association with two jets in pp collisions at $\sqrt{s}=13$ TeV with the ATLAS detector
This Letter reports the first evidence of production of same-sign $W$ boson pairs where at least one of the $W$ bosons is longitudinally polarized and the most stringent constraint to date for the production of two longitudinally polarized same-sign $W$ bosons [...]

First differential measurement of the single $\mathbf{\pi}^+$ production cross section in neutrino neutral-current scattering / T2K Collaboration
Since its first observation in the 1970s, neutrino-induced neutral-current single positive pion production (NC1$\pi^+$) has remained an elusive and poorly understood interaction channel. [...]

Detection of the distant Quasar OP 313 with the first Large-Sized Telescope of CTAO /RE23/CTA-LST Collaboration
Context. Flat Spectrum Radio Quasars (FSRQs) often remain undetected at very-high-energy (VHE, E > 100 GeV) γ rays due to their typically soft spectra and large distance. [...]
