Acceleration of Particles Tracking on CBM Experiment
Roth, Michael ; Kolář, Martin (referee) ; Musil, Petr (advisor)
The focus of this work is to research various methods of particle track reconstruction in the CBM experiment, and the problem of hardware acceleration of these methods. The advantages and disadvantages of the extended methods were discussed and a reconstruction method based on cellular automata and Kalman filters was selected for further study. In particular, the thesis details the development of a simulation model suitable for generating test data to facilitate future implementation of the selected tracking algorithm. Two different particle simulators have been developed and will be used in the following work to calculate the prediction step of the extended Kalman filter and to test the quality of the implemented reconstruction method.

My disertation theses explores the intricate relationship between art, science and photography in the framework of the contemporary culture. Clearly outlined research areas open up the subject to a broader theoretical examination to underpin the artistic strategies that can be employed in the practial research. The resulting artwork interprets the domain of particle physics in a series of artworks. First area of the research delves into the domain of images and seeks to understand the relationship between the images of art and science in a broader sense. Second area investigates ambiguous medium of photography as both tool of science and art. Third area is an overview of the history of representation of the subatomic world and issues related to representing what is in fact unrepresentable. Fourth seeks to find epistemic and conceptual connection between art and science and their interdisciplinary dialogue as Sci-Art. The fifth part introduces artworks that reflect the critical egangement with the theoretical research and the scientific method by building the instrument for the observation of the cosmic rays. Sources for the theoretical framework are largely drawn from the academic literature written in the UK and USA where the topics explored in the theses have been studied in depth. The time scope considered in the theses encompasses 1990's of the 20. century up utill the present day.

Quantum aspects of particle physics models with extended gauge symmetries
Sýkorová, Kateřina ; Malinský, Michal (advisor)
In this thesis, we study quantum aspects of the minimal renormalizable SO(10) Grand Unified Theory with the scalar sector consisting of 45 ⊕ 126 ⊕ 10C. It is an interesting candidate for a theory describing physics beyond the Standard model which has the potential to allow for proton lifetime prediction with Plank- scale-physics-induced theoretical uncertainties confined within the expected one- order-of-magnitude experimental proton lifetime improvement window. With the complete information about the numerical one-loop scalar mass spec- trum and analytical one-loop beta functions of all the dimensionless scalar cou- plings, we formulate consistency criteria that every viable region of the parameter space must satisfy; namely, we require the existence of a stable Standard-model- like vacuum, unification of gauge couplings and robustness of perturbative calcu- lations. Only narrow parameter space regions around symmetry breaking chains with SU(4)C × SU(2)L × U(1)R or SU(3)c × SU(2)L × SU(2)R × U(1)B−L intermedi- ate stages are demonstrated to be potentially realistic. Detailed analysis of the SO(10) Higgs model with 45⊕126 scalar sector indicates a preference for the for- mer option, mainly due to increased perturbative instability and phenomenologi- cally unsuitable values of energy scales predicted in the...

In particular, the thesis details the development of a simulation model suitable for generating test data to facilitate the implementation of the selected tracking algorithm, which was subsequently sped up using distributed computing methods. Two different particle simulation models and a reconstruction algorithm were implemented, with the reconstruction algorithm offering up to 800 per cent speed up factor in respect to the sequential algorithm and up to four orders of magnitude lower memory complexity.

Title: Simulation of noise in the Belle II strip vertex detector Author: Zuzana Gruberová Institute: Institute of Particle and Nuclear Physics Supervisor: RNDr. Peter Kvasnička, Institute of Particle and Nuclear Physics Abstract: This bachelor thesis describes the development of strip noise simulation for the Belle II strip vertex detector (SVD). The overview part of the thesis describes the Belle II experiment and its detector system. The next part summarizes the basic princi- ples of semiconductor detectors with a focus on electronic noise. This section is followed by a more detailed description of Belle II SVD, its noise characteristics and simulation methods. The methods part introduces basic concepts of noise simulation using ma- chine learning methods, in particular, artificial neural networks. The experimental part describes the development and implementation of a production noise generator, and dis- cusses the performance, precision, and alternative solutions. Keywords: particle physics, Belle II, strip detector, noise, simulation, neural network 1
