Elastic Scattering and Total Cross-Section in p+p Reactions : As Measured by the LHC Experiment TOTEM at √<s>=7 TeV(Forward and Diffraction Physics and Cosmic Rays,Multiparticle Dynamics)

概要

論文の詳細を見る
Proton-proton elastic scattering has been measured by the TOTEM experiment at the CERN Large Hadron Collider at √<S>=7 TeV in special runs with the Roman Pot detectors placed as close to the outgoing beam as seven times the transverse beam size. The differential cross-section measurements are reported in the |t|-range of 0.36 to 2.5 GeV^2. Extending the range of data to low t values from 0.02 to 0.33 GeV^2, and utilizing the luminosity measurements of CMS, the total proton-proton cross section at √<S>=7 TeV is measured to be (98.3±0.2^<stat>±2.8^<syst>) mb.
