Title: Elastic differential cross-section measurement at $$\sqrt{s}=13$$ TeV by TOTEM

Abstract

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 GeV²] in four-momentum transfer squared |t|. The efficient data acquisition allowed to collect about 10⁹ elastic events to precisely measure the differential cross-section including the diffractive minimum (dip), the subsequent maximum (bump) and the large-|t| tail. 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 |t_dip| = (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.

Elastic differential cross-section $${\mathrm{d}}\sigma /{\mathrm{d}}t$$ at $$\sqrt{s}=2.76\hbox {TeV}$$ and implications on the existence of a colourless C-odd three-gluon compound state

The proton-proton elastic differential cross section dσ/dt has been measured by the TOTEM experiment at √ s = 2.76 TeV energy with β* = 11 m beam optics. The Roman Pots were inserted to 13 times the transverse beam size from the beam, which allowed to measure the differential cross-section of elastic scattering in a range of the squared four-momentum transfer (|t|) from 0.36 GeV² to 0.74 GeV² . The differential cross-section can be described with an exponential in the |t|-range between 0.36 and 0.54 GeV², followed by a diffractive minimum (dip) at |t_dip| = (0.61 ± 0.03) GeV² andmore »« less

Evidence for non-exponential elastic proton-proton differential cross-section at low |t| and $$\sqrt{s}$$ = 8 TeV by TOTEM

Journal Article Antchev, G. - Nuclear Physics. B

The TOTEM experiment has made a precise measurement of the elastic proton–proton differential cross-section at the centre-of-mass energy √s = 8 TeV based on a high-statistics data sample obtained with the β* = 90 m 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| < 0.2 GeV² with a significance greater than 7 σ. Two extended parametrisations, with quadratic and cubic polynomials in the exponent, are shown tomore »« less
