弹性散射的两个衍射锥与结构对称性猜想

Two diffraction cones of elastic scattering and structural symmetry conjecture

A. P. Samokhin

摘要:

在ISR-LHC能量范围内的弹性质子-质子散射的微分截面的能量依赖性进行了讨论,为固定值的动量转移的区域中的前向衍射锥,在该区域以外的第二个最大值的$dσ/dt$和在附近的dip-bump结构。从现有的实验数据可以看出,在第二个最大值以外的区域中的微分截面具有与前向衍射锥中完全相同的性质,包括存在一个静止点,即我们观察到第二个衍射锥,它与前向峰具有相同的原点。对这一实验事实最简单的自然解释是,高能弹性散射的振幅是两个具有相同状态且仅参数值不同的相似项的和。对于固定的$t$,$dσ/dt$的能量依赖性在浸凸结构的区域中,其中这两个项干扰,证实了上述观察。本文讨论了高能弹性散射振幅的双分量结构的可能起源,并用振幅的结构对称性对此进行了解释。

英文摘要:

The energy dependence of the differential cross-section of elastic proton-proton scattering in the ISR--LHC energy range is discussed for fixed values of momentum transfer in the region of the forward diffraction cone, in the region beyond the second maximum of $dσ/dt$ and in the vicinity of the dip-bump structure. As can be seen from the currently available experimental data, the differential cross-section in the region beyond the second maximum has exactly the same properties as in the forward diffraction cone, including the existence of a stationary point, that is, we observe a second diffraction cone, which has the same origin as the forward peak. The simplest natural explanation for this experimental fact is that the amplitude of high energy elastic scattering is the sum of two similar terms that have the same status and differ only in the values of parameters. The energy dependence of $dσ/dt$ for a fixed $t$ in the region of the dip-bump structure, where these two terms interfere, confirms the above observations. We discuss the possible origin of the two-component structure of the high energy elastic scattering amplitude and explain this by the structural symmetry of the amplitude.
