چکیده
We investigate the collective coordinate quantization of the icosahedrally symmetric B = 7 Skyrmion, which is known to have a ground state with spin 7 2 and isospin 1 2 . We find a particular quantum state maximally preserving the symmetries of the classical solution, and also present a novel relationship between the quantum state and the rational map approximation to the classical solution. We also investigate the allowed spin states if the icosahedral symmetry is partially broken. Skyrme field configurations with D5 residual symmetry can be quantized with spin 32 , giving a realistic model for the ground states of the 7Li/7Be isospin doublet.

We comment on the changes in the constrained model studied earlier when constituent massless vector fields are introduced. The new model acts like a gauge-Higgs-Yukawa system, although its origin is different. PACS 11.10.-z, 12.60.Rc

Generalized parton distributions describe the distribution of partons in the transverse plane. For transversely polarized quarks and/or nucleons, these impact parameter dependent parton distributions are not axially symmetric. These transverse distortions can be related to spin-orbit correlations as well as to (intuitively) to transverse single-spin asymmetries, allowing novel insights into qua...
