Abstract

The TOTEM experiment has performed several measurements related to its physics program in dedicated (high \beta*, low L) LHC fills at $\sqrt{s}$ = 7 TeV. Under various beam and background conditions, the differential elastic (as a function of |t|), elastic, inelastic and total pp cross-sections have been measured. A measurement of the forward charged particle \eta density has also been performed. A summary of these measurements is here reported, as well as the first results from runs at the LHC energy of $\sqrt{s}$ = 8 TeV.
