An improved direct limit on the muon electric dipole moment

2 Collaboration, D. P. Aguillard, T. Albahri +192

A limit on the permanent electric dipole moment (EDM) of the positive muon is presented based on data from the Fermilab Muon g-2 Experiment taken between 2019 and 2020. The trackin…

Final Report on the Measurement of the Positive Muon Anomalous Magnetic Moment at Fermilab to 127 ppb

2 Collaboration, D. P. Aguillard, T. Albahri +192

This report details the final measurement of the muon magnetic anomaly, $a_{μ} = (g_{μ} - 2) /2$ , by the Muon $g - 2$ experiment at Fermi National Accelerator Laboratory (FNAL), using positiv…

Measurements of the Higgs boson production, fiducial and differential cross-sections in the four lepton decay channel using 164 fb $^{- 1}$ of data collected at $s$ = 13.6 TeV with the ATLAS detector

ATLAS Collaboration

Inclusive, differential and production-mode cross-section measurements of the Higgs boson are performed in the $H \to Z Z^{*} \to 4 ℓ$ decay channel. The analysis uses proton-prot…

Measurement of the double Dalitz decay $η \to e^{+} e^{-} e^{+} e^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +689

Using a data sample of $(1.0087 \pm 0.0044) \times 1 0^{10}$ $J / ψ$ events collected with the BESIII detector, we study the rare double Dalitz decay of $η \to e^{+} e^{-} e^{+} e^{-}$ …

Amplitude Analysis of the Isospin-Violating Decay $J / ψ \to γ η π^{0}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +759

Using $(10087 \pm 44) \times 1 0^{6}$ $J / ψ$ events collected with the BESIII detector, we perform the first amplitude analysis of the process $J / ψ \to γ η π^{0}$ . The decay is dominated b…

Radon-induced backgrounds in the NEXT-100 experiment

NEXT Collaboration, C. Cortes-Parra, P. Novella +111

The NEXT-100 detector at the LSC aims at the first competitive search for the \bbnonu decay using a high-pressure \Xe{136} electroluminescent time projection chamber. The first low…
