چکیده

It is shown that the quark–gluon interaction induced by instan-tons leads to the quark anomalous chromomagnetic moment. In the instanton-liquid model for the QCD vacuum, the chromomagnetic moment is µ a = − πf 2αs , where f is the packing fraction of instantons in the vacuum.

Soft Contribution to Quark-Quark Scattering Induced by an Anomalous Chromomagnetic Interaction

We calculate the soft contribution to high energy quark-quark scattering that arises from an instanton-induced quark anomalous chromomagnetic moment. We demonstrate that this is a large contribution, which cannot be neglected for transverse momenta of a few GeV. We discuss the influence of this effect on inclusive particle production.

Three-Loop Chromomagnetic Interaction in HQET

We compute the three-loop QCD corrections to the quark chromomagnetic moment and thus obtain the matching coefficient and the anomalous dimension of the chromomagnetic interaction in HQET. As a byproduct we obtain the three-loop corrections to the quark anomalous magnetic moment.

The anomalous chromomagnetic dipole moment of the top quark in different frameworks and using the b → sγ process as a bench

The anomalous chromomagnetic dipole moment of the top quark in different frameworks and using the b → sγ process as a bench Abstract The anomalous chromomagnetic top quark moment arise from one loop corrections to the vertex ¯ ttg. We give explicit formulae for this anomalous coupling in the framework of the standard model, the two higgs doublet model and the minimal supersymmetric standard mod...
