Measurement of the e+eπ+ππ0e^+e^-\toπ^+π^-π^0 cross section in the energy region from 0.56 to 1.1 GeV with the SND detector

Using data collected by the SND detector at the VEPP-2000 collider, this paper presents a precise measurement of the e+eπ+ππ0e^+e^-\to\pi^+\pi^-\pi^0 cross section in the 0.56–1.1 GeV energy range, yielding improved resonance parameters and a refined calculation of the leading-order hadronic contribution to the muon magnetic anomaly.

First measurement of the strong interaction scattering parameters for the Kd\mathbf{K^-d} and K+d\mathbf{K^+d} systems

This paper presents the first experimental measurement of the strong interaction scattering parameters for the Kd\rm K^-d and K+d\rm K^+d systems using femtoscopic correlation functions from Pb--Pb collisions at sNN=5.02\sqrt{s_{\rm NN}}=5.02 TeV recorded by ALICE, providing crucial benchmarks for low-energy chiral QCD dynamics.

Measurements of differential charged-current cross sections on argon for electron neutrinos with final-state protons in MicroBooNE

The MicroBooNE collaboration presents the first single-differential electron-neutrino charged-current cross-section measurements on argon with final-state protons, reporting a total cross section of [4.1±0.3 (stat.)±1.1 (syst.)]×1039cm2/nucleon[4.1 \pm 0.3 \text{ (stat.)} \pm 1.1 \text{ (syst.)}] \times 10^{-39} \mathrm{cm}^{2}/\mathrm{nucleon} that shows good agreement with standard neutrino event generator predictions.

Constraints on new physics from decays of polarized Λb0Λ_b^0 baryons at the FCC-ee

This paper demonstrates that utilizing the unique polarization of Λb0\Lambda_b^0 baryons produced in Z0Z^0 decays at the FCC-ee, despite comparable statistical sensitivity to LHCb Upgrade II for individual observables, significantly improves constraints on the Wilson coefficients C9()C_{9^{(\prime)}} and C10()C_{10^{(\prime)}} through a broader set of accessible angular observables.

Characterization of the ionization response of argon to nuclear recoils at the keV scale with the ReD experiment

The ReD experiment utilized a compact dual-phase argon Time Projection Chamber irradiated by neutrons to model-independently measure the ionization yield of argon for nuclear recoils between 2 and 10 keV, revealing higher yields at lower energies than previously observed and extending experimental coverage crucial for detecting low-mass Dark Matter.

The ABC of RPV II: Classification of R-parity Violating Signatures from UDD Couplings and their Coverage at the LHC

This paper utilizes the CheckMATE 2 framework to analyze R-parity violating signatures from UDD couplings in the MSSM, revealing that while colored LSPs are well-constrained by current LHC data, electroweakino and slepton LSPs remain significantly under-covered due to a lack of targeted experimental searches.
