Diffractive Dijet Production with Leading Proton in ep Collisions at HERA.
Žlebčík, Radek ; Valkárová, Alice (advisor) ; Chýla, Jiří (referee) ; Levonian, Sergey (referee)
The cross section of the diffractive process e+p → e+Xp is measured at a centre-of-mass energies of 319 GeV, where the system X contains at least two jets and the leading final state proton p is detected in the H1 Very Forward Proton Spectrometer. The measurement is performed in photoproduction defined by photon virtualities Q2 < 2 GeV2 and in deep-inelastic scattering with 4 GeV2 < Q2 < 80 GeV2 . The results are compared to next-to-leading order QCD calculations based on diffractive parton distribution functions as extracted from measurements of inclusive cross sections in diffractive deep- inelastic scattering. A collinear QCD factorization theorem is tested against the measured cross sections and their ratios. 1
Studium difrakčních ep interakcí na hadron-elektronovém collideru
Jansová, Markéta ; Valkárová, Alice (advisor) ; Žáček, Josef (referee)
A new ep collider LHeC is currently planned at CERN. LHeC should comple- ment the physics program of former ep collider HERA and existing hadron-hadron collider LHC. In the LHeC project the collisions of electrons with energy 60 GeV and protons with energy 7 TeV should be studied. The thesis is focused on the study of diffractive charged current deep inelastic scattering interactions, which had already been investigated at HERA collider (H1 experiment), but with un- satisfying statistics. This thesis reproduce Monte Carlo predictions obtained by H1 collaboration for this process and its main goal is calculation of diffractive charged current DIS cross section for future LHeC project.
