Spin and Orbital Angular Momentum Distribution Functions of the Nucleon
M. Wakamatsu, T. Watabe
A theoretical prediction is given for the spin and orbital angular momentum distribution functions of the nucleon within the framework of an effective quark model of QCD, i.e. the…
Do we expect light flavor sea-quark asymmetry also for the spin-dependent distribution functions of the nucleon?
M. Wakamatsu, T. Watabe
After taking account of the scale dependence by means of the standard DGLAP evolution equation, the theoretical predictions of the chiral quark soliton model for the unpolarized an…
The electroproduction of the (1232) in the chiral quark-soliton model
A. Silva, D. Urbano, T. Watabe +2
We calculate the ratios E2/M1 and C2/M1 for the electroproduction of the (1232) in the region of photon virtuality GeV. The magnetic dipole amplitude M1 is also p…
On the Chiral Quark Soliton Model with Pauli-Villars Regularization
T. Kubota, M. Wakamatsu, T. Watabe
The Pauli-Villars regularization scheme is often used for evaluating parton distributions within the framework of the chiral quark soliton model with inclusion of the vacuum polari…
Flavor asymmetry of polarized and unpolarized sea quark distributions in the large-N_c limit
B. Dressler, K. Goeke, P. V. Pobylitsa +3
We summarize recent attempts to calculate the flavor asymmetry of the nucleon's sea quark distributions in the large- limit, where the nucleon can be described as a soliton of…
Symmetry conserving approach to the quantization of the non-topological SU(3) soliton
M. Praszalowicz, T. Watabe, K. Goeke
We reconsider canonical quantization of the rotating soliton in the SU(3) Chiral Quark-Soliton Model. We show that at the level of 1/N_c, in contrast to the SU(2) version of the mo…
