论文摘要
在这封信中,我们报告了等极化夸克准分布函数的结果$ΔU(x,v) - 在大型$ N_C $中,在手性夸克 - 苏利顿模型中计算出的大$ N_C $中的结果。结果表明,与Untarlized Isossinglets分布相比,偏光夸克准分布在核子增强动量$ p_n \至\ infty $(或速度$ v \ to velocity $ v \ to \ infty $)的极限(或速度$ v \ f to velocity $ v \ f to \ infty $)的极限上表现出良好的收敛性。
In this letter, we report the results for the isovector polarized quark quasi-distribution functions $Δu(x,v) - Δd(x,v)$ in the large $N_c$, calculated within the chiral quark-soliton model. It is shown that the polarized quark quasi-distributions present good convergence to the light-cone PDFs in the limit of the nucleon boost momentum $P_N \to \infty$ (or the velocity $v \to 1$), compared to the case of the unpolarized isosinglet distributions.
