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.

弹性散射的两个衍射锥和结构对称性猜想

讨论了ISR-LHC能量范围内弹性质子-质子散射的微分截面的能量依赖性,以了解在前向衍射锥区域内,在第二个最大值以下的区域内动量传递的固定值。 dσ/dŤ并在倾角凹凸结构附近。从当前可用的实验数据可以看出,第二个最大值以外的区域中的微分截面具有与正向衍射锥完全相同的特性,包括存在一个固定点,也就是说,我们观察到第二个衍射锥,其起源与正向峰相同。对于这个实验事实的最简单自然的解释是,高能弹性散射的幅度是状态相同且仅参数值不同的两个相似项之和。的能量依赖性dσ/dŤ对于在这两个项相互干扰的浸凸结构的区域中的固定t,证实了上述观察结果。我们讨论了高能弹性散射振幅的两组分结构的可能起源,并通过振幅的结构对称性对此进行了解释。
