ATLAS vs TOTEM: Disturbing Divergence

Abstract

With use of a new $C+N$ amplitude which correctly accounts for CNI to all orders in $\alpha$ the values of the parameters $ρ^{pp},σ_{\mbox{tot}}^{pp}$ and $B^{pp}$ are analysed on the basis of data published by the TOTEM and ATLAS collaborations at energy $\sqrt{s}=13$ TeV . The result of both joint and separate analyses of these data confirmed, in particular, a noticeable difference between the central values of ${\sigma }_{tot}^{pp}$, as measured by the TOTEM and by the ATLAS-ALFA, reaching up to 8 standard deviations.
