Title: Study of diffractive processes at the ATLAS Experiment Author: Vlastimil Kůs Department: Institute of Particle and Nuclear Physics Supervisor: Mgr. Marek Taševský, Ph.D. Institute of Physics of the Academy of Sciences of the CR, v.v.i. Abstract: A data sample of pp collisions corresponding to an integrated lumi- nosity of 6.75 nb−1 was collected at √ s = 7 TeV using the ATLAS detector at the Large Hadron Collider. Collision events with at least two jets with pT > 20 GeV are used to measure the differential cross section of the diffractive dijet production as a function of the rapidity gap size ∆ηF, the largest forward region extending from |η| = 4.8 devoid of particle activity above threshold momentum cuts, and an estimator of the fractional momentum loss of the scattered proton assuming the single diffractive dissociation (pp → pX), ˜ξ±. Comparisons with various Monte Carlo models reveal that though the region of small ˜ξ± and large rapidity gaps is dominated by diffraction, a contribution form non-diffractive events cannot be neglected. The rapidity gap survival probability is estimated based on data to Monte Carlo comparisons in the −3.2 < log10 ˜ξ± < −2.5 region of the ˜ξ± distri- bution with the ∆ηF > 2 requirement. 1 |
