强子散射振幅的小t性质对实部确定的影响

The effects of the small t properties of hadronic scattering amplitude on the determination its real part

O. V. Selyugin

摘要:

考虑到库仑-强子干涉相的不同形式和可能的自旋翻转贡献,对$3.8 < p_L <6.0 \ $/c和小动量转移的质子-反质子弹性散射实验数据进行了新的分析。结果表明,自旋翻转振幅的大小可以由小$t$处的微分截面的形式确定,并且由$p\bar{p}$散射的实验数据得到的$ρ(s,t)$与基于色散关系的分析\cite{Kroll}的偏差在所有假设下都是守恒的.在$9 < p_L < 70 \ $ GeV/c的质子-质子弹性散射的分析也显示了所检查的影响的形式上的微分截面。

英文摘要:

Taking into account the different forms of the Coulomb-hadron interference phase and the possible spin-flip contribution the new analysis of the experimental data of the proton-antiproton elastic scattering at $3.8 < p_L <6.0 \ $GeV/c and small momentum transfer is carried out. It is shown that the size of the spin-flip amplitude can be determined from the form of the differential cross sections at small $t$, and the deviation of $ρ(s,t)$ obtained from the examined experimental data of the $p\bar{p}$ scattering from the analysis \cite{Kroll}, based on the dispersion relations, is conserved in all xamined assumptions. The analysis of the proton-proton elastic scattering at $9 < p_L < 70 \ $GeV/c also shows the impact of the examined effects on the form of the differential cross sections.
