Phenomenology of Single Spin Effects in Hadron Production at High Energies
| Protvino, 2008. – p. 25 , figs. 10, tables: 6, refs.: 60.

Experimental data on transverse single-spin asymmetry (AN) and hadron polarization (PN) in 68 different inclusive reactions in hh-, hA-, AA- and ell N - interactions have been analyzed in the framework of a phenomenological model. A mechanism for the origin of single spin effects is considered, which takes into account the interaction of massive constituent quarks via their chromomagnetic moment with an effective non-uniform chromomagnetic field of gluon strings, produced after initial color exchange. Quark spin precession in the chromomagnetic field is taken into account. Dynamical masses and anomalous chromomagnetic moments for the constituent u-, d-, s-, c- and b- quarks are estimated.
