Measurements of cross-sections of inelastic and diffractive processes in proton-proton collisions at √s=900, 2760 and 7000 GeV. The fractions of diffractive processes in inelastic collisions were determined from a study of gaps in charged particle pseudorapidity distributions. Single-diffractive events are selected with MX<200GeV/c2 and double-diffractive events defined as NSD events with Δη>3. To measure the inelastic cross-section, beam properties were determined with van der Meer scans using a simulation of diffraction adjusted to data. Note that these are experimental approximations to theoretical concepts -- it is not totally clear whether the data point values are model-independent.
