Closing Convention of the DFG Priority Program 1491 -
Precision Experiments in Particle and Astrophysics with Cold and Ultracold Neutrons

The aim of this Priority Program is to address basic open questions in particle and astrophysics using a specific tool: the neutron, which allows the search for new physics becoming manifest itself as small deviations from expectations. Many neutron physics observables are sensitive to physics beyond the Standard Model emerging from superstrings (hypothetical gauge bosons in large extradimensions), supersymmetry (electric dipole moment prediction at the experimental limit) or other Grand Unified Theories (charge quantisation). Basic properties of the quark-mixing Cabibbo-Kobayashi-Maskawa (CKM) matrix need to be tested. The breaking of symmetries such as parity P, time reversal T and combined charge conjugation and parity symmetry CP shall be investigated. CP violation is a requirement for dynamic generation of the baryon-antibaryon asymmetry of the universe. The research programme focuses on five priority areas, which are directly related to specific physics/astrophysics issues and instrumentation.

During the workshop, we should give reports on all projects and sub-projects, which were performed within the framework of the priority program.

Posters representing the projects are welcome.

In addition, we should give some perspectives of our science, also on what concerns future funding activities.

  • Priority area A:
    CP-symmetry violation and particle physics in the early universe (addressed mainly by the search for the neutron electric dipole moment)
  • Priority area B:
    The structure and nature of weak interaction and possible extensions of the Standard Model (addressed mainly by precise beta decay studies of the neutron)
  • Priority area C:
    Relation of gravitation and quantum theory (probed by investigations of low energy bound states in the gravitational field)
  • Priority area D:
    Charge quantization and the electric neutrality of the neutron (probed by a precision test of the neutron's electric charge)
  • Priority area E:
    New measuring techniques particle detection, magnetometry, neutron optics
