A bstract The three precision measurements of the cross section σ ( e + − → π γ(γ)) using initial state radiation by KLOE collaboration provide an important input for prediction hadronic contribution to anomalous magnetic moment muon. These are correlated both statistical and systematic uncertainties and, therefore, simultaneous use these requires covariance matrices that fully describe correlations. We present construction them determine a combined measurement γ(γ)). find, from this...
We searched for the $μ^+μ^-$ decay of a light vector gauge boson, also known as dark photon, in $e^+ e^- \to μ^+ μ^- γ_{\rm ISR}$ process by means Initial State Radiation (ISR) method. used 1.93~fb$^{-1}$ data collected KLOE experiment at DA$Φ$NE $ϕ$-factory. No structures have been observed over irreducible $μ^+ μ^-$ background.

The Muon g−2 Experiment at Fermilab is expected to start data taking in 2017. It will measure the muon anomalous magnetic moment, aμ=(gμ−2)/2 an unprecedented precision: goal 0.14 parts per million (ppm). new experiment require upgrades of detectors, electronics and acquisition equipment handle much higher volumes slightly instantaneous rates. In particular, it a continuous monitoring state-of-art calibration whose response may vary on both millisecond hour long timescale. system composed...
The Muon $g-2$ experiment, E989, is currently taking data at Fermilab with the aim of reducing experimental error on muon anomaly by a factor four and possibly clarifying current discrepancy theoretical prediction.

Combined with 4$\pi$ coverage movable lead shield, enables quantifiable control ionizing radiation qubit device. Long-time-series tomography measurements these...
The anomalous muon dipole magnetic moment can be measured (and calculated) with great precision thus providing insight on the Standard Model and new physics. Currently an experiment is under construction at Fermilab (U.S.A.) which expected to measure unprecedented precision. One of improvements respect previous experiments come from laser calibration system has been designed constructed by Italian part collaboration (INFN). An emphasis this paper will that in final stages as well start data...

In high energy physics experiments, calorimeters are calibrated to produce precise and accurate results. Laser light can be used for calibration when the detectors sensitive photons in that particular range, which is often case. Moreover, it not unusual detection systems consist of hundreds channels have independently, stringent requirements on distribution system terms temporal spatial stability, timing. Furthermore, economic factor ease production taken into account. We present a prototype...
