Title: "The Totem experiment: Proton Proton cross section measurement and diffraction at LHC"
------------------------------------------------------------------------------------------------------------------
Abstract:

The Totem experiment, installed in the interaction point 5 at LHC, has charged particle detectors 
that cover a pseudorapidity range up to 6.4 for inelastic detection, and two set of Roman Pots 
stations, one at 147 meters and the second at 220 meters from IP5, on both beams that could 
measure scattered protons. The 2010-2011 data tacking campaign allowed the measurement 
of the differential P-P elastic cross section from 0.02<t<2 and using the optical theorem the total 
cross section. The inelastic detectors allowed the direct measurement of the inelastic cross section.
The telescope T2 could measure the charged particle density in the pseudorapidity range 5.3<eta<6.4.
Evidence of single diffraction and double pomeron exchange has been seen.
