Precise Measurement of the Total Cross Section and the Coulomb Scattering at the Lhc∗
نویسندگان
چکیده
A precise measurement of the total cross section and the Coulomb scattering at LHC requires the observation of elastically scattered particles at extremely small angles (14 μrad, −t ≤ 0.01 GeV for the first case; 3 μrad, −t ≤ 0.0006 GeV) for the second one). In this paper a very high-β insertion optics which fulfills both conditions is presented. A feasibility study, including the acceptance of the detectors, for an experiment to be installed in IR1 or IR5, is also presented.

Measuring Elastic Scattering in the Coulomb Nuclear Interference (CNI) Region in ATLAS – Total Cross Sections and Luminosity
The Large Hadron Collider (LHC) will provide proton-proton collisions for the experiments installed at the interaction points (IP). The ATLAS detector is designed to detect high pt reactions and will focus on the discovery of the Higgs boson and new physics. However ATLAS is now also complemented by detectors in the very forward region to measure small angle elastic scattering. This will give a...
متن کاملTOTEM: The experiment to measure the total proton–proton cross section at LHC
TOTEM is an experiment dedicated to the measurement of the proton–proton total cross section (σ TOT ) at LHC, i.e. the probability that two protons interact at the center of mass energy of 14 TeV. In addition to that, it will also study the proton–proton elastic scattering and diffractive dissociation processes. TOTEM foresees specific measurements and experimental techniques which are very dif...

Recently the ATLAS experiment was complemented with a set of ultra-small-angle detectors located in “Roman Pot” inserts at 240m on either side of the interaction point, aiming at the absolute determination of the LHC luminosity by measuring the elastic scattering rate at the Coulomb Nuclear Interference region. Details of the proposed measurement the detector construction and the expected perfo...

In the present work, the scattering differential cross section has been investigated for ion-multi electron atoms collision in the charge transfer channel. For this purpose, an active electron model was implemented and the collision process was considered as a three-body impact in the high energy range. A semi-classical formalism was used with the eikonal distorted wave function to describe the...

A second-order approximation to the Faddeev-Watson-Lovelace treatment of the rearrangement channel is used in a three-body scattering cross sections. In this formalism, the Three-body wave function is expressed by three coupled integral equations, the Faddeev equations, which contian the two-body (off-shell) transition amplitudes, and proved the uniqueness of their solutions. This amplitude c...
