Projects for Master students in the Nikhef B-physics (LHCb) group
date: May 2014
This is an overview with all available Master student projects in the Nikhef B-physics (LHCb) group.
If you have your own research proposal, need more detailed information on the
(availability) of individual proposals or would like to discuss about other available
projects in the group you are always welcome to contact
either the contact person for the project and/or the Nikhef B-physics group leader:
Marcel Merk [e-mail: i93_at_nikhef.nl, Tel 020-5925107, Nikhef room N2xx]
For an overview of the theses written in the Nikhef B-physics group you can look at the Nikhef LHCb theses page
Master projects in the Nikhef B-physics group
| 1) Study of long-living particles |
|---|
Supervisors: Wouter Hulsbergen (staf) and Veerle Heijne (PhD)
Research description:
Supersymmetry is potentially the key to understand the Dark Matter in the Universe. Within the SUSY framework, long-living supersymmetric particles can exist, which can be detected by the LHCb detector. The search for these particles will be performed on the recent data set recorded in 2012, and some work is also needed on the trigger selection, to prepare for data taking in 2015, when the LHC will be running at a higher center-of-mass energy.
For this project computer skills are needed. The ROOT programme and C++ and/or Python macros are used. You become part of our research group (~5 persons); we have weekly video meetings with colleagues at CERN.

| 2) Searching for Lorentz Invariance Violation with Bs -> J/psi phi decays |
|---|
Supervisors: Gerhard Raven (staf), Jeroen van Tilburg (Postdoc)
Research description:
The measurement of CP violation occurring in decays of the type Bs-->J/psi phi is a flagship analysis in the LHCb experiment. However, no-one in LHCb has tested whether CPT symmetry is violated. CPT symmetry is tightly connected to the principle of Lorentz invariance. Lorentz invariantz violation would become visible if the decay rate would show any dependency to a fixed direction in space. In this project the CP violation analysis is extended to test for Lorentz Invariance violation.
For this project computer skills are needed. The ROOT programme and C++ and/or Python macros are used. This is a project that is closely related to the larger effort at Nikhef (~5 people) of measuring phi_s with Bs->J/psiPhi decays. Weekly video meetings with CERN coordinate the efforts within the LHCb collaboration.
