The Quark Color Magnetic Moment
The quark color magnetic moment is examined in the framework of the interaction of a quark with a constant external color magnetic field. Quark and gluon propagators in the external field are evaluated and shown to lead to a g-Ii 3a s r&5E a field dependent anomalous magnetic moment u = 2mc 4T m2 where B is the external field strength. Comparison is made with the behavior of the electron anomal...

متن کاملTop Quark Amplitudes with an Anomalous Magnetic Moment
The anomalous magnetic moment of the top quark may be measured during the first run of the LHC at 7 TeV. For these measurements, it will be useful to have available tree amplitudes with tt and arbitrarily many photons and gluons, including both QED and color anomalous magnetic moments. In this paper, we present a method for computing these amplitudes using the Britto-Cachazo-Feng-Witten (BCFW) ...
متن کاملMagnetic vortex in color-flavor locked quark matter
Within Ginzburg-Landau theory, we study the structure of a magnetic vortex in color-flavor locked quark matter. This vortex is characterized by winding of the SU(3) phase in color-flavor space, as well as by the presence of a color-flavor unlocked condensate in the core. We estimate the upper and lower critical fields and the critical Ginzburg-Landau parameter that distinguishes between type I ...
متن کاملColor magnetic corrections to quark model valence distributions.
We calculate order αs color magnetic corrections to the valence quark distributions of the proton using the Los Alamos Model Potential wavefunctions. The spin-spin interaction breaks the model SU(4) symmetry, providing a natural mechanism for the difference between the up and down distributions. For a value of αs sufficient to produce the N −∆ mass splitting, we find up and down quark distribut...
