Measurement of muon (anti-)neutrino charged-current quasielastic-like cross section using off-axis NuMI beam at ICARUS / ICARUS Collaboration
This paper presents the first neutrino cross-section measurement from the ICARUS detector at Fermilab, using NuMI (Neutrinos at the Main Injector) beam data collected from two beam operation periods corresponding to $2.5\times10^{20}$ protons-on-target in neutrino beam mode. [...]

First evidence of the decay $B^+ \to \pi^+ e^+ e^-$ / LHCb Collaboration
The first evidence for the decay $B^+\to\pi^+ e^+ e^-$ is reported using proton-proton collision data recorded by the LHCb experiment at centre-of-mass energies of 7, 8 and 13 TeV, corresponding to an integrated luminosity of 9 fb$^{-1}$. [...]

Advances in photocathode development for PICOSEC Micromegas precise-timing detectors / Lisowska, M. (CERN ; Baskent U.) ; Guerra, F. (CERN ; INFN, Turin) ; Gurpinar, A. (CERN ; Middle East Tech. U., Ankara) ; Zavazieva, D. (Technion) ; Aleksan, R. (IRFU, Saclay) ; Aune, S. (IRFU, Saclay) ; Bortfeldt, J. (Munich U.) ; Breskin, A. (Weizmann Inst.) ; Brunbauer, F.M. (CERN) ; Brunold, M. (Pavia U. ; INFN, Pavia) et al.
The PICOSEC Micromegas detector is a precise-timing gaseous detector that combines a Cherenkov radiator, a semi-transparent photocathode and a Micromegas amplification stage, targeting time resolutions of tens of picoseconds for minimum ionising particles (MIPs). [...]

(Greifswald U.) ; Herlert, A. (FAIR, Darmstadt ; Darmstadt, GSI) ; Holt, J.D. (TRIUMF ; McGill U.) et al.
We present the first determination of the $N = 50$ empirical shell gap at $Z = 48$ by precise mass measurements of the neutron-deficient cadmium isotopes $^{96-98}$Cd with the ISOLTRAP mass spectrometer at ISOLDE-CERN, including the first precise determination of the excitation energy of the $25/2^+$ isomer in $^{97}$Cd.

Flavour changing charged current decays at LHCb / Mitreska, Biljana (Manchester U.)
Semileptonic $b$-hadron decays proceed via charged-current interactions and provide powerful probes for testing the Standard Model and searching for New Physics effects. [...]

Search for electroweakinos in compressed-spectrum scenarios with low-momentum isolated tracks in proton-proton collisions at $ \sqrt{s} = $ 13 TeV / CMS Collaboration
A search for supersymmetric electroweakinos is performed using events with a low-momentum (soft) isolated track and large missing transverse momentum, targeting nearly mass-degenerate higgsino-like charginos and neutralinos. [...]
