Elastic differential cross-section measurement at √s = 13 TeV by TOTEM
Original language description
The TOTEM collaboration has measured the elastic proton-proton differential cross section dσ/dt at √s = 13 TeV LHC energy using dedicated β∗ = 90 m beam optics. The Roman Pot detectors were inserted to 10σ distance from the LHC beam, which allowed the measurement of the range [0.04 GeV2, 4 GeV 2] in four-momentumtransfer squared |t|. The average nuclear slope has been found to be B = (20.40± 0.002 stat ± 0.01syst) GeV−2 in the |t|-range 0.04–0.2 GeV2. The dip position is |tdip|=(0.47±0.004stat±0.01syst) GeV2. The differential cross section ratio at the bump vs. at the dip R =1.77±0.01stat has been measured with high precision. The series of TOTEM elastic pp measurements show that the dip is a permanent feature of the pp differential cross-section at the TeV scale.
