The Muon (g-2) Experiment, E989 at Fermilab, will measure the muon anomalous magnetic moment a factor-of-four more precisely than was done in E821 Brookhaven National Laboratory AGS. result appears to be greater Standard-Model prediction by three standard deviations. When combined with expected improvement hadronic contributions, should able determine definitively whether or not is evidence for physics beyond Standard Model. After review of motivation and basic technique, which use storage...
Abstract The workshop “Shedding light on X17” brings together scientists looking for the existence of a possible new particle, often referred to as X17.

Abstract During 2022 data taking (Run III) PADME searched for a resonant production and visible decay of the X17 particle into e + - . A precise knowledge within 1% uncertainty number positrons was required observation. To that purpose, an array 2 × 6 Timepix3 (total 512 1536 pixels) hybrid pixel detectors operated in data-streaming mode with ToA resolution 1.56 ns every employed. Two methods acquisition were developed. frame-based method, integrating hits each individual predefined period...
The anomalous magnetic moment of the muon is one most precisely measured quantities in experimental particle physics. Its latest measurement at Brookhaven National Laboratory deviates from Standard Model expectation by approximately 3.5 standard deviations. goal new experiment, E989, now under construction Fermilab, a fourfold improvement precision. Here, we discuss details future and its current status.
The PADME experiment at the LNF Beam Test Facility searches for dark photons produced in annihilation of positrons with electrons a fix target. strategy is to look reaction $e^{+}+e^{-}\rightarrow γ+A'$, where $A'$ photon, which cannot be observed directly or via its decay products. electromagnetic calorimeter plays key role by measuring energy and position final-state $γ$. missing four-momentum carried away can evaluated from this information particle mass inferred.

PADME is a fixed-target, missing-mass experiment at the Laboratori Nazionali di Frascati (LNF) to search for evidence of dark photons. It has collected first set commissioning data in 2018/2019 which will also be used preliminary analysis. expected reach sensitivity up $10^{-8}$ $\epsilon^2$ (kinetic mixing coefficient) low-mass photons ($\sim$ few MeV). Here we describe PADME's design, status experiment, and future plans.
