摘要:

在程函形式主义,它提供了弹性和非弹性通道之间的联系,非弹性的质心能量的依赖关系进行了研究。由于缺乏非弹性实验数据集,目前的分析是基于实验信息,涵盖了大范围的能量,即30 $<$ $\sqrt{s}$ $\leq$ 1800 GeV的全相空间多重性分布。我们的研究结果表明,非弹性的减少是由于产生的半硬相互作用所产生的胶子的散射携带只有很小一部分的动量,从他们的父母质子的minijets。估计非弹性的替代方法进行了讨论和预测的LHC的能量。

英文摘要:

The dependence of the inelasticity in terms of the center of mass energy is studied in the eikonal formalism, which provides connection between elastic and inelastic channels. Due to the absence of inelasticity experimental datasets, the present analysis is based on experimental information available on the full phase space multiplicity distribution covering a large range of energy, namely 30 $<$ $\sqrt{s}$ $\leq$ 1800 GeV. Our results indicate that the decrease of inelasticity is consequence of minijets production from semihard interactions arising from the scattering of gluons carrying only a very small fractions of the momenta from their parent protons. Alternative methods of estimating the inelasticity are discussed and predictions to the LHC energies are presented.
