Measurement of the CKM angle $\gamma$ in $B^\pm\to D K^\pm$ and $B^\pm \to D \pi^\pm$ decays with $D \to K_\mathrm S^0 h^+ h^-$
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 $K_{\mathrm S}^0K^+K^-$ (commonly denoted $K_{\mathrm S}^0 h^+h^-$).

Hunting down the X17 boson at the CERN SPS / NA64 Collaboration
Recently, the ATOMKI experiment has reported new evidence for the excess of $e^+ e^-$ events with a mass $\sim$17 MeV in the nuclear transitions of $^4$He, that they previously observed in measurements with $^8$Be. [...]

Measurement of the production cross section of 31 GeV/$c$ protons on carbon via beam attenuation in a 90-cm-long target / Acharya, A (NA61/SHINE Collaboration)
The production cross section of 30.92 GeV/$c$ protons on carbon is measured by the NA61/SHINE spectrometer at the CERN SPS by means of beam attenuation in a copy (replica) of the 90-cm-long target of the T2K neutrino oscillation experiment. The employed method for direct production cross-section estimation minimizes model corrections for elastic and quasi-elastic interactions. [...]

The Present and Future of Four Tops / Banelli, Giovanni ; Salvioni, Ennio ; Serra, Javi ; Theil, Tobias ; Weiler, Andreas
We study the phenomenology of a strongly-interacting top quark at future hadron and lepton colliders, showing that the characteristic four-top contact operators give rise to the most significant effects. [...]
