论文摘要
在扩展的Parton模型的框架中描述了核子形状随着能量增加的形状演变的情景，该框架始终考虑了Partons的横向运动。在LHC的能量$ e $上，核子具有球体的形式，该形式在横向方向上以$ \ sqrt {\ ln \！e} $的形式扩展，并在纵向方向上以$ E $线性增长。随着能量的进一步增加，建立了帕顿的相关行为模式，从而阻止了纵向生长。同时，横向的膨胀变为$ \ ln \！e $，并且在核子内部沿着中心轴的方向在核子内形成了大多数没有parton的空心。获得相应参数的数值估计值。
A scenario of evolution of the shape of nucleons with increasing energy is described in the framework of extended parton model, which consistently takes into account the transverse motion of the partons. At the energy $E$ up to LHC, the nucleons have the form of a spheroid which expands as $\sqrt{\ln \!E}$ in the transverse directions and grows linearly in $E$ in the longitudinal direction. With a further increase in the energy a mode of correlated behavior of the partons is established, which stops the longitudinal growth. Simultaneously, the expansion in the transverse directions changes to $\ln \!E$, and a hollow mostly free of partons is formed inside the nucleons along the central axis in the direction of their motion. Numerical estimates of the corresponding parameters are obtained.
