Abstract
The TOTEM experiment at CERN’s Large Hadron Collider is dedicated to forward hadronic phenomena. The tree pillars of its physics programme are: an accurate measurement of the total pp cross-section, a measurement of elastic scattering in a wide kinematic range and a wide study of diffractive processes. TOTEM plans to run at all LHC optics conditions with special emphasis on the high β∗ optics runs that enables TOTEM to make measurements of the total cross-section using the luminosity-independent method. A key element of this method is the extrapolation to t = 0 GeV2 of the differential elastic cross-section. An adequate parametrization of the differential elastic cross-section and a treatment of the Coulomb part is presented and applied to the two high β∗ optics, 1535 and 90 m. The expected precision on the total cross-section measurement for the two optics is about 5% and about 1%, respectively. The TOTEM physics in the early LHC runs will include measurement of high-|t| elastic scattering and high-mass diffraction and studies of the forward charged particle multiplicy.
