Diffractive measurements in ATLAS

Several diffractive measurements in ATLAS are discussed. Using a diffractive enhanced event sample, the diffractive fraction of the inelastic cross section is determined to be in the range 25-30 % dependent on what model is used. Rapidity gap studies give similar percentages. The differential cross...

description Several diffractive measurements in ATLAS are discussed. Using a diffractive enhanced event sample, the diffractive fraction of the inelastic cross section is determined to be in the range 25-30 % dependent on what model is used. Rapidity gap studies give similar percentages. The differential cross section as a function of the rapidity gap size has been determined at the hadron level. The diffractive cross section is roughly 1 mb per unit of gap size for gap sizes bigger than 3.5 units.
