论文摘要
核和库仑振幅的结合描述了带电的哈隆的弹性散射。众所周知，在非常向前的范围内，核真实和库仑零件相互作用在确定实际部分在$ | t | = 0 $的大小中至关重要的作用。但是，超过$ | t | = 0 $，真实和虚构的核幅度具有不同的$ t $依赖项，我们表明，在LHC Energies中，由组合$ T_C（T）+T_R^n（s，t）= 0 $在PP过程中可以在背景中被视为想象中的部分时可能会观察到的零零。该观察结果限制了在此远期范围内的实际部分。
Elastic scattering of charged hadrons is described by the combination of nuclear and Coulomb amplitudes. It is well know that at the very forward range the nuclear real and Coulomb parts interplay a crucial role in the determination of the magnitude of the real part at $|t|=0$. However, beyond $|t|=0$ the real and imaginary nuclear amplitudes have different $t$ dependencies and we show that at LHC energies the zeros formed by the combination $T_C(t)+T_R^N(s,t)=0$ in pp process can be potentially observed when the background due to the imaginary part is removed. This observation constrains the real part at this forward range.
