散射振幅自旋结构测定的若干问题和NICA实验

Some problems of determination of the spin structure of the scattering amplitude and experiments at NICA

O. V. Selyugin

摘要:

在对高能质子-质子和质子-反质子弹性散射散射振幅结构的不同假设下,对现有实验数据进行了检验,得到了库仑-强子干涉区散射振幅实部与虚部之比rho(s,t)的值。结果表明,由3.8 <PL <6.2GeV/c的质子-反质子散射实验数据得到的ρ(s,t)与色散分析的偏差在所有检验的假设中都是值得关注的。

英文摘要:

The existing experimental data are examined under different assumptions about the structure of the scattering amplitude of the proton-proton and proton-antiproton elastic scattering at high energy to obtain the value of rho(s,t), the ratio of the real to imaginary part of the scattering amplitude in the Coulomb-hadron interference region. It is shown that the deviation of rho(s,t) obtained from the experimental data of the proton-antiproton scattering at 3.8 < P_L <6.2 GeV/c from the dispersion analysis is concern in all examined assumptions.
