Fitting of multiple vertices with RAVE

B-Mesons mainly decay in a B->D chain. Since the D decay vertex is displaced from the B decay vertex the determination of the B vertex gets biased if tracks from the D decay are included in the fit. The RAVE package allows in principle to fit multiple vertices and hence separate tracks from B and D decays. It should be studied if this feature can be used to improve the vertex resolution.

Monitoring and analysis of performance changes of the PXD Detector during a run

During a run the silicon sensors of the PXD (Pixel vertex detector) suffer from radiation damage which leads to gain changes or even to fatal damages of a pixels. From existing data the PXD properties needs to be extracted and changes should be correlated with the performance of the accelerator.

Optimization of the fitting procedures to determine ΔΓ in B0d decays

Find the best strategy to measure the width difference ΔΓ between even and odd CP eigenstates of the B0d comparing various analyses methods, e.g. :

Two component fit, weighting, moments, multi-parameter log-likelihood fit, etc.

Schieren Bildgebungsstudien im Rahmen des AWAKE-Experiments

The AWAKE group at Max Planck Institute for Physics (MPP) is looking for a student to perform calibration measurements on a schlieren imaging system. Schlieren imaging systems allow observation of weak spatial inhomogeneities in transparent materials by determining the ray deflection angles caused by the gradient of the index of refraction in the material. Schlieren imaging has been used in applications ranging from viewing turbulent air from candle flames to observation of the shock cones of supersonic aircraft. AWAKE uses schlieren imaging in an attempt to measure the transverse plasma density distribution of LASER ionized rubidium vapor. The student would be responsible for: setup of a schlieren imaging system at MPP, selection of calibration test samples, performing the calibration measurements, analysis of the collected data, and publication of technical note for the AWAKE collaboration.

Vorbereitung der Analysen fuer das LEGEND Experiment

Das LEGEND Experiment wird z.Zt. zur Suche nach nutrinolosem
Doppelbetazerfall mit Hilfe von Germaniumdetektoren augfgebaut.
Die LEGEND Gruppe am MPI untersucht in Muenchen zur Vorbereitung
der Analysen in speziell konzipierten Teststaenden
die fundamentalen Eigenschaften der Ladungstraeger in Germanium.
Zur Simulation von Halbleiterdetektoren hat die Gruppe u.a.
das open-source Programmpaket SSD.jl entwickelt.
Bachelorarbeiten koennen vergeben werden fuer
 -- spezialisierte Datennahme und Qualitaetskontrolle,
 -- Simulation von bestimmten Detektorkonfigurationen,
 -- Arbeiten am SSD.jl Paket [incl. Einarbeitung in die Sprache Julia],
 -- Simulationen fuer die Physik von LEGEND.
Interessenten moechten bitte Dr. Iris Abt [isa"at"mpp.mpg.de] und
Dr. Oliver Schulz[oschulz"at"mpp.mpg.de] kontaktieren.
