Double-sided silicon microstrip detectors for track reconstruction in COMPASS - implementation of clustering algorithms

The COMPASS collaboration operates at the CERN Super Proton Synchrotron a complex detector setup including silicon microstrip detectors for the observation of charged particles trajectories. Due to high beam intensity and reactions with several particles in the final state, many particles cross within the same time window, and the observed hit pattern must be analysed using elaborate clustering and background suppression algorithms. While after many years of running, the implemented algorithms have been refined and enhanced in several iterations, there is known room for improvement, and a need for working over the related software. Depending of the pre-knowledge for this bachelor thesis, this may be a well-defined part of it, or the overall structure (within the analysis C++ framework).

Investigation of systematics of using an electromagnetic calorimeter for measuring a high-energy cross-section revealing pion dynamics

The TUM group of the COMPASS collaboration at the CERN Super Proton Synchroton specialized in the analysis of high-energy scattering reactions for a better understanding of the strong interaction and the quark-gluon structure of hadrons. The lightest hadron, the pion, consists mainly of light up- and down-quarks and has surprising properties linked to the breaking patterns of chiral symmetry. For the investigation of one of them, the chiral anomaly, a special scattering type has been examined with a charged and a neutral pion in the final state. The neutral pion decays almost promptly into two photons, which are observed in an electromagnetic calorimeter. The analysis of the data depends on a good understanding of this detection, and on the separation of background. In this thesis, the dependence of different background suppression scenarios is to be studied, supporting the analysis for understanding an important aspect of the subatomic structure of matter.

Pion polarisability from COMPASS high-statistics data

The COMPASS collaboration operates a complex spectrometer setup in order to investigate reactions of high-energy pion and muon beams with various targets. Final states with a single photon produced along the scattering of the beam particle, with only tiny momentum transfer to the target, serve to determine the electromagnetic polarisabilities of the scattered particle. This is the most precise way of accessing the pion polarisability, which is an important fundamental quantity of the microcosmos. Data have been taken in the years 2009 and 2012, with low and high statistics, respectively. The existing analysis of the 2009 data is to be applied to the 2012 data, with some need for refining the methods due to the higher statistics. Main part of the work is programming in a C++ based framework, and handling large data sets on computer clusters.
