At the LHC energy of $/sqrt{s} = 7$ TeV, under various beam and background conditions, luminosities, and Roman Pot positions, TOTEM has measured the differential cross-section for proton-proton elastic scattering as a function of the four-momentum transfer squared t . The results of the different analyses are in excellent agreement demonstrating no sizeable dependence on the beam conditions. With the luminosity from CMS, the elastic cross-section was determined to be (25.4 $/pm$ 1.1) mb, and using in addition the optical theorem, the total cross-section was derived to be (98.6 $/pm$ 2.2) mb.
