Evidence for Non-Exponential Elastic Proton-Proton Differential Cross-Section at Low |t| and $\sqrt{s}$ = 8 TeV by TOTEM
The TOTEM experiment has made a precise measurement of the elastic proton-proton differential cross-section at the centre-of-mass energy $\sqrt{s}$ = 8TeV based on a high-statistics data sample obtained with the $\beta$* = 90m optics. Both the statistical and systematic uncertainties remain below 1%...

| description | The TOTEM experiment has made a precise measurement of the elastic proton-proton differential cross-section at the centre-of-mass energy $\sqrt{s}$ = 8TeV based on a high-statistics data sample obtained with the $\beta$* = 90m optics. Both the statistical and systematic uncertainties remain below 1%, except for the t-independent contribution from the overall normalisation. This unprecedented precision allows to exclude a purely exponential differential cross-section in the range of four-momentum transfer squared 0.027 < |t| < 0. 2GeV$^2$ with a significance greater than 7 $\sigma$. Two extended parametrisations, with quadratic and cubic polynomials in the exponent, are shown to be well compatible withthe data. Using them for the differential cross-section extrapolation to t = 0, and further applying the optical theorem, yields total cross-section estimates of (101.5 $\pm$ 2.1) mb and (101.9 $\pm$ 2.1) mb, respectively, in agreement with previous TOTEM measurements. |
