Elastic differential cross-section measurement at root s=13 TeV by TOTEM
Original language description
The TOTEM collaboration has measured the velastic proton-proton differential cross section d sigma/dt at root s = 13 TeV LHC energy using dedicated beta* = 90 m beam optics. The Roman Pot detectors were inserted to 10s distance from the LHC beam, which allowed the measurement of the range [0.04 GeV2; 4 GeV2] in four-momentum transfer squared vertical bar t vertical bar. The efficient data acquisition allowed to collect about 10(9) elastic events to precisely measure the differential cross-section including the diffractive minimum (dip), the subsequent maximum (bump) and the large-vertical bar t vertical bar tail. The average nuclear slope has been found to be B = (20.40 +/- 0.002(stat) +/- 0.01(syst)) GeV-2 in the vertical bar t vertical bar-range 0.04-0.2 GeV2. The dip position is vertical bar t(dip)vertical bar = (0.47 +/- 0.004(stat)+/- 0.01(syst)) GeV2. The differential cross section ratio at the bump vs. at the dip R = 1.77 +/- 0.01(stat) 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.
