A muon collider would enable the big jump ahead in energy reach that is needed for a
fruitful exploration of fundamental interactions. The challenges of producing muon collisions …

The muon magnetic anomaly, a μ=(g μ− 2)/2, plays a special role in the history of the
Standard Model (SM). Precise calculations and measurements of this fundamental quantity …

We present a new measurement of the positive muon magnetic anomaly, a μ≡(g μ-2)/2,
from the Fermilab Muon g-2 Experiment using data collected in 2019 and 2020. We have …

A search for chargino–neutralino pair production in three-lepton final states with missing
transverse momentum is presented. The study is based on a dataset of s= 13 TeV pp …

A search for charginos and neutralinos at the Large Hadron Collider using fully hadronic
final states and missing transverse momentum is reported. Pair-produced charginos or …

We report an improved measurement of the free neutron lifetime τ n using the UCN τ
apparatus at the Los Alamos Neutron Science Center. We count a total of approximately 38× …

The CDF Collaboration recently reported a new precise measurement of the W-boson mass
MW with a central value significantly larger than the SM prediction. We explore the effects of …

In this paper, we discuss how windows in Euclidean time can be used to isolate the origin of
potential conflicts between evaluations of the hadronic-vacuum-polarization (HVP) …

The Fermi National Accelerator Laboratory (FNAL) Muon g− 2 Experiment has measured the
anomalous precession frequency a μ≡(g μ− 2)/2 of the muon to a combined precision of …

A bstract With the long-standing tension between experiment and Standard-Model (SM)
prediction in the anomalous magnetic moment of the muon a μ recently reaffirmed by the …
