【 摘 要 】

In this note, we summarize and compare various model predictions for 𝑝𝑝 total cross-section $𝜎_{ext{tot}}^{pp}$, giving an estimate of the range of predictions for the total cross-section, $𝜎_{ext{tot}}^{pp}$ expected at the LHC. We concentrate on the results for $𝜎_{ext{tot}}^{pp}$ obtained in a particular QCD based model of the energy dependence of the total cross-section, including the effect of soft gluon radiation. We obtain the range of predictions in this model by exploring the allowed range of model parameters. We further give a handy parametrisation of these results which incidentally spans the range of various other available predictions at the LHC as well.
