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 $\rho^{pp},\sigma_{\mbox{tot}}^{pp}$ 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 $\sigma^{pp}_{tot}$, as measured by the TOTEM and by the ATLAS-ALFA, reaching up to 8 standard deviations.
