Title: Study of jet fragmentation and inclusive jet production in heavy-ion colli- sions with the ATLAS experiment Author: Mgr. Radim Slovák Institute: Institute of Particle and Nuclear Physics Supervisor: Mgr. Martin Spousta, Ph.D., Institute of Particle and Nuclear Physics, Charles University Abstract: This thesis presents two measurements - measurement of the jet frag- mentation functions and inclusive jet production in heavy-ion collisions. The frag- mentation functions are measured in Pb+Pb and pp collisions with the ATLAS detector at the LHC. The distributions are measured as a function of jet trans- verse momentum and rapidity. The analysis utilises an integrated luminosity of 0.14 nb−1 of Pb+Pb data and 4.0 pb−1 of pp data collected in 2011 and 2013, respectively, at the same centre-of-mass energy of 2.76 TeV. Modest but signif- icant centrality-dependent modifications of fragmentation functions in Pb+Pb collisions with respect to those in pp collisions are seen. Measurements of the yield and nuclear modification factor, RAA, for inclusive jets are performed us- ing 25 pb−1 of pp data at √ s = 5.02 TeV and 0.49 nb−1 of Pb+Pb data at √ sNN = 5.02 TeV. The jets are measured over the transverse momentum range of 100-1000 GeV in six rapidity intervals covering |y| < 2.8. The magnitude of the RAA...
