关于高能散射中一个可能的驻点
On a Possible Stationary Point in High-Energy Scattering
摘要：
我们讨论了一个奇怪的观测结果：在从ISR到LHC（包括ISR和LHC）的能量范围内，质子-质子弹性散射的微分截面在转移动量t =-0.21 GeV^2和7.5 mb/GeV ^2的水平上几乎保持能量无关。后一个值可以被认为是13 TeV下dsigma/dt的预测值。我们还得到了一个下限的前PP斜率在13 GeV。
英文摘要：
We discuss a curious observation: at energies from the ISR and up to the LHC, inclusively, the differential cross-section of elastic proton-proton scattering remains almost energy-independent at the transferred momentum t =-0.21 GeV^2 at the level of 7,5 mb/GeV^2.The latter value can be considered as a prediction for dsigma/dt at 13 TeV. We also obtain a lower bound for the forward pp slope at 13 GeV.
