Chapter 1Introduction

Braun, Nils

Pages: 1 –6

[Since people have first observed their surroundings, they have been trying to grasp the inner structures that drive the world around them. Mankind has developed complex theories that describe and predict the universe—from the macroscopic theories of galaxy cluster formations to the microscopic...

Chapter 2Experimental Setup

Braun, Nils

Pages: 7 –26

[The task of the Belle II experiment is to search new physics in particle decays at unprecedented high precision. The following chapter summarizes the basic concepts how this task is performed and which techniques are used for this. The information given in this chapter is described in more...

Chapter 3Foundations

Braun, Nils

Pages: 27 –49

[The following chapter summarizes the basic mathematical and algorithmic foundations used throughout this thesis. The goal is to present the topics to a level of detail which helps to understand the work presented in the following chapters. For a more complete and thorough discussion, references...

Chapter 4Fast Reconstruction for the High Level Trigger

Braun, Nils

Pages: 51 –91

[The High Level trigger (HLT) plays a crucial role for the success of an experiment, as pointed out in Sect. 2.2. Its decision logic, which defines whether a collision event is accepted or discarded, defines which physical results can be extracted from the collected data and whether a certain...

Chapter 5Event Timing

Braun, Nils

Pages: 93 –115

[The event time describes the time the collision producing a physically interesting event with a positive trigger decision happened. Because of the integration time of the subdetectors, each recorded event includes the data of more than a single collision.]

Chapter 6Combinatorial Kalman Filter

Braun, Nils

Pages: 117 –174

[The Combinatorial Kalman Filter (CKF) is a tracking concept that combines track finding and track fitting in a search-tree-based algorithm. It is used by many high energy physics experiments (Mankel and Spiridonov in Nucl Instrum Methods Phys Res Sect A Accel Spectrom Detect Assoc Equip...

Chapter 7Conclusion

Braun, Nils

Pages: 175 –177

[With the start of Phase 3 in the beginning of 2019, Belle II will deliver its crucial part for the study of multiple interesting physics models and theories. Its planned instantaneous luminosity and its clean e+e-\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym}...
