论文摘要
在ISR-LHC能量范围内，讨论了弹性质子 - 蛋白散射的差异横截面的能量依赖性，以了解在正向衍射锥体中的动量转移的固定值，在$dσ/dt $的第二个最大值和浸入凹陷结构附近的第二个区域中。从当前可用的实验数据可以看出，超出第二个最大值的区域的差分横截面具有与正向衍射锥体完全相同的特性，包括存在固定点的存在，即，我们观察到第二个衍射锥，该衍射锥与正向峰具有相同的来源。对于这个实验事实的最简单的自然解释是，高能弹性散射的幅度是两个具有相同状态的相似术语的总和，仅在参数值的值中有所不同。在浸入式结构的区域中，对于固定$ t $的$dσ/dt $的能量依赖性在其中这两个术语进行干扰证实了上述观察结果。我们讨论了高能弹性散射振幅的两分量结构的可能起源，并通过振幅的结构对称性来解释这一点。
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.
