Measurement of the CKM angle $\gamma$ in $B^\pm\to D K^\pm$ and $B^\pm \to D \pi^\pm$ decays with $D \to K_\mathrm S^0 h^\pm h^\mp$ /LHCb Collaboration
A measurement of $CP$-violating observables is performed using the decays ${B^\pm \to D K^\pm}$ and ${B^\pm \to D \pi^\pm}$, where the $D$ meson is reconstructed in one of the self-conjugate three-body final states $K_\mathrm S^0\pi^+\pi^-$ and $K_\mathrm S^0 K^+ K^-$ ($h^\pm h^\mp = \pi^\pm \pi^\mp, K^\pm K^\mp$). The decays are analysed in bins of the $D$-decay phase space, leading to a measurement that is independent of the modelling of the $D$-decay amplitude. [...]

Reconstruction and identification of boosted di-$\tau$ systems in a search for Higgs boson pairs using 13 TeV proton$-$proton collision data in ATLAS / ATLAS Collaboration
In this paper, a novel technique, referred to as the di-$\tau$ tagger, is designed to reconstruct and identify hadronically decaying $\tau^+\tau^-$ pairs with a large Lorentz boost in the ATLAS experiment at the Large Hadron Collider. [...]

The Neutrino Magnetic Moment Portal: Cosmology, Astrophysics, and Direct Detection / Brdar, Vedran ; Greljo, Admir ; Kopp, Joachim ; Opferkuch, Toby
We revisit the physics of neutrino magnetic moments, focusing in particular on the case where the right-handed, or sterile, neutrinos are heavier (up to several MeV) than the left-handed Standard Model neutrinos. [...]
