This book was released on 2014 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: A measurement of the total pp cross section at the LHC at √s=7 TeV is presented. In a special run with high-?* beam optics, an integrated luminosity of 80 ?b-1 was accumulated in order to measure the differential elastic cross section as a function of the Mandelstam momentum transfer variable t . The measurement is performed with the ALFA sub-detector of ATLAS. Using a fit to the differential elastic cross section in the.
