Improved results on Higgs boson pair production in the 4b final state / CMS Collaboration
Measurements of Higgs boson pair (HH) production in the four bottom quark (4b) final state are presented using proton-proton (pp) collision data at $\sqrt{s}$ = 13.6 TeV collected by the CMS experiment at the CERN LHC, corresponding to an integrated luminosity of 62 fb$^{-1}$. [...]

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). [...]
