论文摘要
在没有修改的情况下，应用了弹性质子 - 蛋白散射的单位扩展的Bialas-Bzdak模型，以描述TEV能量范围内的弹性质子 - 抗激碰合碰撞的差异横截面，并推断这些差分横截面到LHC能量。在这项依赖模型的研究中，我们发现在2.76和7 TEV能量处的弹性质子 - 蛋白碰撞数据的差异横截面与外推到这些能量的弹性质子 - 抗细胞碰撞的差异横截面显着不同。在此扩展的Bialas-Bzdak模型的帮助下，弹性质子 - 蛋白质差异截面在弹性质子 - 抗抗球菌碰撞的理论差异内，借助这种扩展的Bialas-Bzdak模型推断至1.96 TEV能量。这些结果在一起为弹性散射幅度的交叉散射幅度至少在7.08 Sigma水平上提供了一个依赖模型的但统计学上的显着证据。从重建的Odderon和Pomeron振幅中，我们确定相应总和差异截面的$ \ sqrt {s} $依赖性。
The unitarily extended Bialas-Bzdak model of elastic proton-proton scattering is applied, without modifications, to describe the differential cross-section of elastic proton-antiproton collisions in the TeV energy range, and to extrapolate these differential cross-sections to LHC energies. In this model-dependent study we find that the differential cross-sections of elastic proton-proton collision data at 2.76 and 7 TeV energies differ significantly from the differential cross-section of elastic proton-antiproton collisions extrapolated to these energies. The elastic proton-proton differential cross-sections, extrapolated to 1.96 TeV energy with the help of this extended Bialas-Bzdak model do not differ significantly from that of elastic proton-antiproton collisions, within the theoretical errors of the extrapolation. Taken together these results provide a model-dependent, but statistically significant evidence for a crossing-odd component of the elastic scattering amplitude at the at least 7.08 sigma level. From the reconstructed Odderon and Pomeron amplitudes, we determine the $\sqrt{s}$ dependence of the corresponding total and differential cross-sections.
