Hadronic light-by-light scattering contribution to the muon anomalous magnetic moment from lattice QCD.
The most compelling possibility for a new law of nature beyond the four fundamental forces comprising the standard model of high-energy physics is the discrepancy between measurements and calculations of the muon anomalous magnetic moment. Until now a key part of the calculation, the hadronic light-by-light contribution, has only been accessible from models of QCD, the quantum description of th...
متن کاملSupersymmetry and the anomalous anomalous magnetic moment of the muon.
The recently reported measurement of the muon's anomalous magnetic moment differs from the standard model prediction by 2.6 sigma. We examine the implications of this discrepancy for supersymmetry. Deviations of the reported magnitude are generic in supersymmetric theories. Based on the new result, we derive model-independent upper bounds on the masses of observable supersymmetric particles. We...
متن کاملThe Bnl Muon Anomalous Magnetic Moment Measurement
The E821 experiment at Brookhaven National Laboratory is designed to measure the muon magnetic anomaly, aμ, to an ultimate precision of 0.4 parts per million (ppm). Because theory can predict aμ to 0.6 ppm, and ongoing efforts aim to reduce this uncertainty, the comparison represents an important and sensitive test of new physics. At the time of this Workshop, the reported experimental result f...
متن کاملEstimate of the hadronic vacuum polarization disconnected contribution to the anomalous magnetic moment of the muon from lattice QCD
The quark-line disconnected diagram is a potentially important ingredient in lattice QCD calculations of the hadronic vacuum polarization contribution to the anomalous magnetic moment of the muon. It is also a notoriously difficult one to evaluate. Here, for the first time, we give an estimate of this contribution based on lattice QCD results that have a statistically significant signal, albeit...
متن کاملQCD improved determination of the hadronic contribution to the anomalous magnetic moment of the muon
We present the results of a new evaluation of the anomalous magnetic moment aμ = (gμ − 2)/2 of the muon where the role of input data needed in the evaluation is lowered in the interval between 1.2 and 3.0GeV below charm threshold. This is achieved by decreasing the size of the weight function in the dispersion integral over the experimental ratio R(s) by subtracting a polynomial from the weight...
