Measurement of the total cross section and ρ-parameter from elastic scattering in pp collisions at √s=13 TeV with the ATLAS detector

Popis výsledku v původním jazyce

In a special run of the LHC with β⋆=2.5β⋆=2.5 km, proton–proton elastic-scattering events were recorded at s=13s ​=13 TeV with an integrated luminosity of 340~upmu { ext {b}}^{-1} using the ALFA subdetector of ATLAS in 2016. The elastic cross section was measured differentially in the Mandelstam t variable in the range from −t=2.5⋅10−4−t=2.5⋅10−4 GeV22 to −t=0.46−t=0.46 GeV22 using 6.9 million elastic-scattering candidates. This paper presents measurements of the total cross section σtotσtot​, parameters of the nuclear slope, and the ρρ-parameter defined as the ratio of the real part to the imaginary part of the elastic-scattering amplitude in the limit t→0t→0. These parameters are determined from a fit to the differential elastic cross section using the optical theorem and different parameterizations of the t-dependence.
