横坐标空间中的电荷和纵向动量分布

Charge and longitudinal momentum distributions in transverse coordinate space

Chandan Mondal, Narinder Kumar, Harleen Dahiya, Dipankar Chakrabarti

摘要:

利用由软壁AdS/QCD预言构造的波函数的重叠,研究了核子的光前夸克-双夸克模型中横坐标空间中$u$和$d$夸克的电荷分布.我们还得到了横坐标空间中质子和中子的电荷分布,并与碰撞参数空间中的分布进行了比较。进一步,我们利用横坐标空间中的波函数研究了纵向动量分布。我们还展示了不同撞击的$u$和$d$夸克的明确费米子和玻色子贡献。

英文摘要:

We investigate the charge distributions for the $u$ and $d$ quarks in transverse coordinate space in a light-front quark-diquark model for the nucleons using the overlaps of the wave functions constructed from the soft-wall AdS/QCD prediction. We have also obtained the charge distributions for proton and neutron in transverse coordinate space and compared it with the distributions obtained in impact-parameter space. Further, we study the longitudinal momentum distributions using the wave functions in the transverse coordinate space. We have also shown the explicit fermionic and bosonic contributions for different struck $u$ and $d$ quarks.
