Title: Study of proton-proton and heavy-ion collisions with the ATLAS experi- ment at the LHC Author: Mgr. Petr Balek Department: Institute of Particle and Nuclear Physics Supervisor: Doc. RNDr. Jiří Dolejší, CSc. Abstract: The presented results show a suppression in a production of charged hadrons in heavy-ion collisions with respect to the production measured in proton- proton collisions. Lead-lead data at √ sNN = 2.76 TeV were recorded by the AT- LAS experiment at the LHC in 2010 and 2011 and they have a total integrated luminosity of 0.15 nb−1 , and proton-proton data at √ s = 2.76 TeV were recorded in 2011 and 2013 having an integrated luminosity of 4.2 nb−1 . The results are presented in wide transverse momentum (0.5 < pT < 150 GeV) and pseudorapid- ity (|η| < 2) ranges, and also in different centrality intervals of Pb+Pb collisions. Nuclear modification factor RAA shows a clear pT-dependence with a minimum at around 7 GeV, however above 60 GeV, it reaches a plateau with no significant pT-dependence. As a function of |η|, the RAA is flat over whole pT region. Keywords: ATLAS detector, heavy-ion collisions, charged-hadron spectra, nuclear modification factor RAA

Study of pp and PbPb collisions at LHc
Balek, Petr ; Dolejší, Jiří (advisor) ; Spousta, Martin (referee)
In the present work we study the identification of the particle using deposited charge per unit length in the Pixel detector (part of the ATLAS detector) wich can offer an almost analogous read-out of the deposited charge. First, we parametrically describe the dependences of the deposited charge to reduce the volume of the data used in further analysis. Then we use these parameters as an input for particle identification. We elaborate the method of the identification that allows us to say in most of the cases whether the particle passing through the detector was pion, kaon, or proton. This method can be reproduced using Athena tool that has been written.

Developing desktop Java applications with rich GUI
BÁLEK, Petr
This work aims to show examples of the advanced options that offer longer supplied as standard Java packages, where the greatest emphasis is placed on the package javax.swing and java.awt. In this work, of course, created and given exemplary examples that are built on the above packages. Circuits, which work as the animation, effects static and dynamic convolution filters, gradients, alpha composition, and other another topics.
