The Quark Color Magnetic Moment
نویسنده
چکیده
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 anomalous magnetic moment in strong fields. Possible phenomenological consequences for hadron mass splittings are discussed. (Submitted to Phys.

Hypercentral Constituent Quark Model and Isospin for the Baryon Static Properties
So far the static properties of hadrons have been introduced in various models. The static properties of hadrons (charge radius, magnetic moment, etc.) are useful for understanding the quark structure of hadron. In this work we have introduced the hypercentral constituent quark and isospin dependent potentials. Here constituent quarks interact with each other via a potential in which we have ta...
متن کاملSingle Spin Effects in Collisions of Hadrons and Heavy Ions at High Energy
Experimental data on transverse single-spin asymmetry, hyperon polarization and vector meson alignment in h+h, h+A and A+A-collisions have been analyzed. A new mechanism for the origin of single spin effects is proposed, which takes into account the interaction of massive constituent quarks via their chromomagnetic moment with an effective inhomogeneous chromomagnetic field of strings, produced...

The failure of simple constituent-quark models' to explain' the new experimental values of X and magnetic moments ' contrasts sharply with the remarkable success of the naive constituent-quark model in describing the nucleon and A magnetic moments"" and the hadron mass spectrum. " " The underlying dynamical reasons for this success are not understood and it all may be accidental, ' However, the...
متن کاملThe role of electroweak penguin and magnetic dipole QCD penguin on hadronic b Quark Decays
This research, works with the effective Hamiltonian and the quark model. Using, the decay rates of matter-antimatter of b quark was investigated. We described the effective Hamiltonian theory which was applied to the calculation of current-current (Q1,2), QCD penguin (Q3,…,6), magnetic dipole (Q8) and electroweak penguin (Q7,…,10) decay rates. The gluonic penguin structure of hadronic decays ...
