Particle- and Astroparticle Physics and Computing (B1-B6)

The activities can be characterized by the following categories :

  • B1 Physics analysis (software-oriented)
    Students join the DESY ATLAS or CMS groups and participate in one of the physics analyses carried out in the areas of electroweak and Higgs physics, standard model measurements, QCD, top physics and searches for new physics. Alternatively they join the DESY Belle II or the International Linear Collider group preparing physics analyses of future data. Students joining the astroparticle groups participate in physics analysis related to high-energy neutrino and gamma-ray emission from astrophysical objects. The B1 students analyse real and/or simulated data and contribute to specific analysis tasks such as optimising the signal to background separation or fitting possible new physics signals to the data.

  • B2 Data processing (software-oriented)
    The students join the same experimental groups as mentioned in B1 but focus more on developing specific software that is needed to effectively perform the physics measurements. The students contribute to the development of algorithms and codes in specific areas such as reconstructing physics objects (particles) from the detector data, event triggering, detector calibration, data quality monitoring and optimal and efficient physics analysis based on the identified particles. A further topic is event simulation.

  • B3 Development of experimental equipment (hardware-oriented)
    Students join experimental groups working on the development of future detectors, e.g. ATLAS and CMS at the High-Luminosity LHC, the ILD, BELLE II, ALPS II, IceCube and CTA. Groups at DESY work on silicon trackers, gaseous detectors, data acquisition systems, and testbeams. The students contribute to laboratory and testbeam setups, prepare and perform test measurements with prototypes, analyse and interpret the measured data.

  • B4 Research on Accelerators
    Students join groups engaged in the development of accelerators. Activities include prototype projects for an e+e- linear collider with an emphasis on superconducting rf cavities and projects for beamline instrumentation and plasma wakefield acceleration. In Zeuthen students can actively participate in the development of the photo injector test facility PITZ.

  • B5. Theory of Elementary Particles and Astroparticle Physics
    Students acquire some elementary insight into topics from the wide spectrum of research carried out in Hamburg at the DESY Hamburg theory group (collider phenomenology, particle cosmology, string theory) and in Zeuthen at the two elementary particle theory groups DESY Zeuthen theory group and NIC institute and the Astroparticle Physics theory group . Depending on previous knowledge, activities typically range from further reading, with discussions of theoretical concepts and research methods, to participation in simple research projects. Students are encouraged to indicate in their application if they have a preference for a particular field of research pursued in the theory groups. Often at least a minimum pre-knowledge (e.g. from lecture courses) is required in order to be selected for a project in a particular field.

  • B6. Computing
    At DESY Hamburg students can participate in various areas of scientific computing such as Grid and Cloud, data management (dCache), high performance (HPC) and GPU, and in infrastructures for analysis. At Zeuthen students participate also in tests and software development for powerful parallel computers

  • Typical fractions of the number of offered projects in the different areas are:
    B1(30%), B2(8%), B3(36%), B4(12%), B5(10%) and B6(4%).
