چکیده
In this paper we consider gauge invariant nonminimal couplings of the vector and axial vector components of the torsion tensor to the Standard model fermions and abelian gauge fields. We then determine the constraints on the unknown parameters of the torsion action from its contribution to the muon anomaly. The bounds on the torsion mass and coupling obtained from muon anomaly are finally compared with direct bounds obtained from high energy collider experiments.

Torsion contraints from the recent measurement of muon anomaly
In this paper we consider gauge invariant nonminimal couplings of the torsion field to the Standard model fermions and U(1) gauge bosons. We then determine the constraints on the unknown parameters of the torsion action from its contribution to the muon anomaly. The bounds on the torsion mass obtained from muon anomaly are finally compared with those obtained high energy collider experiments. E...
متن کاملTorsion contraints from the recent precision measurement of the muon anomaly
In this paper we consider non-minimal couplings of the Standard Model fermions to the vector (trace) and axial vector (pseudo-trace) components of the torsion tensor. We then evaluate the contributions of these vector and axial vector components to the muon anomaly and use the recent precision measurement of the muon anomaly to derive constraints on the torsion parameters.

متن کاملThe Muon Anomalous Magnetic Moment and the Standard Model
The muon anomalous magnetic moment measurement, when compared with theory, can be used to test many extensions to the standard model. The most recent measurement made by the Brookhaven E821 Collaboration reduces the uncertainty on the world average of aμ to 0.7 ppm, comparable in precision to theory. This paper describes the experiment and the current theoretical efforts to establish a correct ...
متن کاملImplications of Bnl Measurement of Δa Μ on Scalar Leptoquark Mass and Coupling
Abstarct Recently BNL have measured the muon magnetic moment anomaly with increased precision. The world average experimental value at present shows a discrepancy of 43(16)× 10 from the Standard Model [SM] value. In this paper we investigate the implications of this difference on a class of scalar leptoquark interactions to SM quark-lepton pair. We find that for leptoquarks in the few hundred G...
